Lots of options....
The other guys are right, you have a lot to chose from. You really need to decide what kind of riding you will be doing, all purpose, all weather, terrain... number of miles...etc. At your height and weight, you really don't have many restrictions. You could piece something together for a decent price. I've seen some pretty fat deals on some of last years frames... including the Look 361i, but you can get a nice 853 steel, such as the Fuji Roubaix Pro, or Lemond or there are several to pick from. Or, if you go aluminum... the choices are about endless. But get most importantly get something that fits, and do not worry about 105 vs ultegra.
Bottom line is that you are gonna get all sorts of suggestions. I think the best bet would be for you to narrow it down to a few, then you could probably get some more objective opinions here.
