I know that fit is a complicated subject, etc, etc, but I'm just looking for some broad ideas of what to start looking for.
The -2cm rule is pretty good. It works for almost everyone and is the general rule when you're starting out on the track. Once you get some experience and decide to plunk your own cash on a frame, look for something that has a top tube 1cm shorter than your road bike. Set it up with a stem that's the same length as the one on your road bike. You can even go for a steeper drop if you like as well.
My own track setup goes like this. 57cm top tube, 100mm stem, 1cm bottom bracket drop, and a 19 cm drop from seat level to bar tops.
My road bike is 55cm seat tube, 56.5 cm top tube. 110mm stem, 27 cm bottom bracket height, and a 10cm drop from seat level to bar tops.
Just some numbers to fudge around with. I stick to short sprint events on the track and have short legs/long torso. To start with, try to mimic your road set up as close as possible.
