Hi, I'm a new user on this forum but after reading back a few pages I realized that it provides a depth of knowledge. I apologize for the length of my initial post. I've spent the last week reading multiple forums and can say that I've picked up a lot of knowledge so far. I still consider myself a novice photographer but realized that I caught a bug to take solid pictures after returning from my 3 week trip overseas. I just recently bought a HD camcorder (Sony HDR-SR12) which I love and ended up taking over 2,000 digital stills with it. I was not expecting much and good thing because while it's certainly not terrible, the quality was lackluster.
I do have experience with dSLR's and Canon's in particular. I purchased the original Digital Rebel in 2003 (300D), used that for roughly 1.5 years or so then upgraded to the XTi. While I'm not a complete newbie and understand some of the basic terms, for the most part though with the original Digital Rebel I treated it much like a P&S and shot mostly in Auto. Only with the XTi did I start to dabble with using manual settings. I ended up giving the XTi to my sister who's expecting her first child next month to take some nice pictures of her firstborn. After seeing some of the quality pictures that others have taken I'm interested in investing in a solid body.
I know that the body is secondary to the glass but I want a body that I can grow into and use for 3-5 years. I suffer from the alpha male tendency of being drawn into the newer and flashier tech goods as I'm sure some of you do but to remain cost effective I want this body to last. I know that I didn't tap the full potential of the Digital Rebel, let alone the XTi. I considered going the Nikon route to try something new but realized that my best interest would to stay with Canon to share glass with my sister's camera. Some questions.
1. I fully expect the 40D to have a sharp learning curve. I have invested in the book 'Understanding Exposure' as a starting point and plan on taking a class or two this fall. Would the 40D still be too much camera for me to learn and grow on?
2. I'm not working on any fixed budget but on the other hand I do not want to pay for something that I will not use. Therefore I'm looking at the 40D instead of the 5D. I may skip the kit with the 28-135 as I've been told that while it's a solid overall lens, it's not wide enough nor is the reach long enough. I may end up with the kits with the intention to sell the lens. The primary lens I'm looking at is the 17-55 f/2.8 as my walkaround lens. Good choice?
3. My primary interests are architecture (Buildings, bridges, towers, etc), landscapes (beach scenes), sports (golf in particular), and portraits. Therefore I have the lenses that I eventually want to get as I learn as the 10-22, the 60, and the 55-250. I'm thinking with those 3 in addition to the 17-55 I'll have a wide enough range with little to no overlap and enough variety. Ok selection?
4. While I've seen the 40D in person, I've yet to hold one. My cousin keeps telling me not to get it since it's a heavy camera and that holding it will be a chore. I realize that it's noticeably heavier then the two that I've used in the past and being an Asian male I don't have the largest hands in the world, but for those of you that have it, does it bother you? I travel more these days and I plan on taking 200-300 shots per photographing session, probably no more then 2x a month. So I'm not going to be a frequent user like some of you, I would venture to say no more then 10,000-15,000 actuations a year.
5. In addition to the body, the 17-55 and the 3 lenses that I am interested in, what else should I take note of in terms of accessories to add? I would say I'm at 3/10 in terms of using Photoshop but have the full intention of learning how to use it better.
Thank you all for any insight you can provide me in terms of the 40D and general observations I should follow and I'll be sure to check this thread frequently and add any additional questions as I go along.

I love my 17-55mm as a walk-around lens and the 10-22mm has been a great wide angle lens for me with this camera. I also enjoy taking pictures of structures, beach scenes, and have taken many pictures on the golf course with the 40D.
