I think you want the seattube to be pretty much the same as you would ride on your usual frame [your legs don't get longer just because you're on a pursuit frame :) ]. Next you want to make sure the top tube is roughly the same length as your usual ride - maybe a bit shorter???. Then the head tube height depends on how aggressive the slope of the frame is.
After saying that i think you're best off trying any frame before you buy
I ride one which is roughly your size, you're welcome to try it for size
