I am also a short person, and the problem you'll find is that you can make the TT only so short on a track frame for 700c wheels without messing up the geometry, specifically head and seat tube angles. I have a 49cm Bianchi pista Concept with a 52.3cm effective TT and reasonable 74 / 76 head and seat tube angles and 28mm fork offset. I also have a 43cm Motobecane Messenger with a 50.3cm effective TT, but it has 72 / 75 angles and 45mm fork offset. About the only thing you can do to remedy the situation is to use a shorter stem and a bar with shorter reach and drop, which is what I did with a Leader frame that has a very long TT. Because this frame has a short head tube, steep 74 degree head angle and short 28mm fork offset, my riding position relative to the front wheel axle is still good with this setup.
