Vandersteen question.

I got some advice in another thread to get rid of my speakers. It was kind of rude, as my question concerned digital devices, but it's probably true. My system: Rotel 951 CD player, Creek 5350SE integrated amp, PSB 5T speakers. Interconnects are silver serpents from better cables. Speaker cables are AR for bi-wiring, but some Ixos is on the way, as some of you called it the best bargain in speaker wire.
I've been looking into the Vandersteen line. I'm in a smallish room, 12X15X 8 high. I live in an area where there are no dealers within 150 miles, but I am planning a trip to see and hear for myself. My questions are: Will my Creek amp run the various models, 1b, 1c, 2c, 2ce, signature series, and with the size of my room would a smaller one be right? I'm not even sure of the difference between some of the models, like 1b and 1c, and 2 and 2ce, 2ci etc. If any of you have some thoughts I would appreciate the help.
