Please Help! MTBR buying a new road bike! Sizing??NeedySpeedy

I'm about to purchase a new road bike. I can get an awesome deal on the Jamis Eclipse. My question is about sizing, something I dont know much about - I'm a mountain biker, but I want to do more road.
My bike now is old junk. The center of the BB to the top of the top tube is 58mm. The top tube measured from the center of the seatpost along the top tube to the center of the headtube looks like 57mm. I have a 110mm stem on it. I dont feel cramped or over extended, but I dont know if I have the right fit on this bike either.

The Jamis has a 57 & 59 size. The 57 is 57mm from the center of the BB to the top of the top tube and a 57mm top tube center to center. The 59 has a dimension of 59mm BB to top and 58mm top tube. The 57 comes with a 110mm stem & 172.5 cranks and the 59 comes with 120mm stem and 175 cranks. I dont have the luxury of trying each bike. I'm hoping someone can help me make a decision. Is it better to go slightly smaller when faced with this kind of choice? It seems like the choice to go with is the 57, but when I'm spending this kind of money I'd like to be sure. Will it be too small?

Thanks for any replies. Oh by the way I'm 6'-0" with a 32"-33" inseam.

Well, my advice is to go with the smallest frame you can ride. You can always raise the seat, get a longer stem, etc. A bike that's too big is just too gol'darn big. Also, the smaller the frame is the lighter, stiffer, stronger it'll be.
