I have shot arch work for 10 years+. My thoughts.
Gear is the last thing to worry about here. I'll get to it last then.
Knowing your market area and what the work is worth is paramount. Join ASMP, APA or any other trade photo group which has a strong architecture base. ASMP has a specialty arch group of about 400 members who discuss things daily via a yahoo group. A wealth of information. Don't be a lone cowboy. You will make too many mistakes. None of this is rocket science. It's been done, just follow some leads, make it work for you and your clients but in the same vane as your fellow architectural photographer colleagues.
Start by going here:
http://asmp.org/find-a-photographer/search?city=&state=FL&country=0&radius=0&spec1=9&spec2=0&conjunction=and&lname=&chapter_member=&submit=Searchand call some of these photographers to get honest answers on what do the different Florida markets bear price wise, what do clients expect, learn some of the jargon specific to shooting architecture. Correct communication is important to have with your clients, and there is a lot to good business practices.
Each type of client for arch work is looking for something different. An architect wants a photographer who is acting as a visual extension to their original concept. Interior designers, homebuilders, realtors, magazines all want something a little different, they all have different needs for their target audience.
As a landscape shooter, you will be inclined to shoot sites more as postcards at first perhaps (example, the image on your site) which is ok, but only a small fraction of what the clients want.
While you can get away with only shooting natural light, not all sites are designed with the best interior and exterior lighting. So you may be limited in capabilities from site to site. HDR is cool and all, but most great arch work happened long before that even existed and the images were still stunning without it. So don't expect that HDR will be a savior to well framed, great time of day type of shots. What is lost so often in HDR arch work is mood and feeling because the shooter is trying too hard to keep exposure on all parts of the scene which leaves a flat and lifeless feeling sometimes.
I strongly believe a great arch shooter is someone who is passionate about the content itself. It's not that they try to be interested, it's that they are interested.
Then we get to licensing. Architects nowadays almost expect unlimited usage outside of paid advertising. They will certainly work with you on terms for editorial usage (because magazines want as much for free from the architects or designers themselves). I know that there is a market for real estate photography at the higher end but there is NO market for it below, don't waste your time.
Client relations is key. Get to know them. Spend the time with them. They will be repeat clients over and over. That's what this segment is about.
There is no way for me to write everything I have ever learned in this segment here in a forum, but plenty of outlets out there to get the needed info, they are just specialized.
Now about the gear, who cares really. There are great arch shooters who use 4x5 trans and neg, many who now use 21-24mp cameras with T/S lenses and some with medium format digital. This really is the last thing to worry about. It's not a selling point to say you have the most expensive camera, blah, blah. Someone who lights a scene well can shoot with a 5D and get a better shot.
I do believe perspective corrections are important in this type of work. Not all shots need it. A lot of lifestyle arch work, editorial in feel and nature are about selling the desire to have things and how to live, and how better a person's life will feel if they live in a home with x,y,z style. But a 4x5 camera and color neg film is as easy as it gets. It doesn't require many frames for this work. Sure your H3DII-39 will make nice files but learn to make it work for this segment.
To be completely honest, a lot of architects use photos in presentations, web, maybe print portfolio. They don't advertise much if ever. They really don't need 150meg files, They really don't care. I just read the other day on the ASMParch group a photographer said a long time client (high end client at that) asked why he kept sending such huge files all the time, files coming from a 5DII. I can't stress enough, clients don't care about our gear. They want stunning images, that's it. Along with a great working experience with you and little hassle.
And lastly for now, find a style, an approach, something that sets you apart. There are a lot of really good shooters in this country. But if you want to get work from clients who already hire other shooters, you need to give them a reason (and don't let that reason be because you're less expensive!)
Susan Carr is an arch shooter in Chicago and also does a seminar tour on the business side of things. Find a city where she is speaking or get that exact type of info from other sources.
Invent your own image style that will make clients want to hire you, but don't reinvent the wheel on the business side, that's been done and all there for your taking. Clients want some continuity in working with photographers on the business side. They hire us to create and solve their visual needs which is what sets us apart.
Added: Sure you can go the route of no assistant, but trust me when I say, you'll want one for every half or full day shoot. Clients want more images done these days, so someone has to be the gofer. Sweep leaves, wash windows, pull weeds, turn lights on/off. Run around and find the site's mechanical engineer, move your gear to the next view while you're shooting the current view. You are endlessly more productive on site if there is just one peron helping you. Without that, time is wasted farting around solving the most mundane crap on site. An assistant is really a small production charge in a day. Most clients understand.
Everything that can go wrong on site, does go wrong. So be prepared, which is having an assistant.

I’m seeking suggestions/direction about:
Equipment required to do the best of work
Successful methods of marketing my services - seek architects, developers, high end realtors??????
Other ideas I’m not aware of to ask yet
I feel I have enough energy to start a new career and I want it to be a profitable one - thus Architectural Photography seems a natural transition to me.
I have been experimenting with local structures, some of the condos on the beach here in Naples, FL are beautiful, and find it fascinating but different than Landscpaes.
Hoping my knowledge of HDR might allow me to focus solely on Natural Light rather than getting into a menagerie of lighting setups.
I want to do this solo, not with an assistant.
Observations from folks actually earning a living from Architectural work and shooting digitally would be greatly appreciated.
Thanks,
Jack
