That's about right. Some young guys would say 56, some old ones might say 60, but 57 or 58 will get you close enough without a lot of stem and seatpost heroics. Basically, you want a virtual (or horizontal) top tube between 57 and 58 cm. There will be plenty of stems, handlebars, seatposts, and saddles for fine-tuning the fit when you're ready for that.
dtrain, your Roubaix looks really nice. 6600 is a pretty safe bet, being newer and just plain working better than that old 9-speed stuff. If my wife wasn't complaining about too many bikes, I'd want it for myself.
