Howdy Brandy,
Welcome to the forum! I can see that you are already well on your way to developing your own style from looking at the photos in your galleries. Lots of nice work in there.
You seem to enjoy a nice shallow depth of field in most of your portraits, so some faster Canon lenses could make your work easier and mean less time in post production. For example, the EF 28mm f/1.8 USM, EF 35mm f/2, EF 50mm f/1.4 USM, and the EF 85mm f/1.8 USM would probably make the sorts of images that you like to create easier to produce. You can read about these lenses at one more more of these sites:

These are not zoom lenses, so if you want to include more or less of the scene in the frame, you have to walk around a bit, but since most of your work is outside, that probably won't be a problem. All of these should produce good center sharpness and contrast with nice soft backgrounds at around f/2 or so.
As others have said, your camera body is fine for what you are trying to do. If you find yourself shooting more weddings, you may want to upgrade to one of the xD bodies so that your digital Rebel is not upstaged by uncle Joe's 50D, for example. However, that's a very minor perception issue. As long as you are confident shooting the body you have, there's really no reason to change it. I've always said that what's in front of the body (the lens and subject) and what's behind it (the photographer) have far greater impact on image quality than the body itself.
Oh, there are some really good books on photography business that are worth reading. I really liked The Real Business of Photography
, by Richard Weisgrau. I've also just started Best Business Practices for Photographers
, by John Harrington, and so far, it's excellent! We learned a lot from classes at Betterphoto.com
as well as training from the PPA
.
Hope this helps.
