Heh - thanks. There are still some techniques I want to improve, but things are coming together.
I use a Canon EOS 20D with an MT-E2 wireless flash transmitter and a 420EX flash. It's good gear, but not their absolute top of the line in any of their respective categories. I think the most critical piece here is the remote flash since it allows you far, far more flexibility with the single most difficult aspect: the light. You need adequate light with the right properties and you often need it coming from places you can't be with the camera.
I discuss a lot of this in more depth in another post
Hope that's helpful! It's a lot of fun, so I'm glad to share information...
