The sizes are not generic. They depend on the frame geometry. For instance a 52cm TT bike is not the same size as a 52cm touring bike. The general rule is that while straddling the top tube, there should be 1-1.5 in. between the top tube and your bits.
Since your torso is short and legs long, you may want to go a size smaller than normally recomended for your height. I'm 5'9.5" and have a 34 inch inseam and have found I prefer a slightly smaller bike with a higher saddle.
Regardless, fit is very personal and no definite advice can be given over a message board. I would suggest asking someone at a local bike shop to fit you properly. Improper fit can cause all sorts of pains and problems.

Agreed, many bike shops have fit bike kits or similiar to fit, the quick method that gets you in the ball park is to measure your inseam then multiply by .67 then covert it to cm by multipling by 2.54. This at least will get you in the ballpark for the correct frame size.
