What pedals should I upgrade to for racing on the road and possibly track?
I would recommend the Look Keo Classic pedals if you are not hyper-sensitive to the weight.  They offer a carbon version if you decide to spend the extra bucks for the lighter version.  Popular and well-liked pedal with the extremely common Look cleat style.

I picked my pair up from probikekit.com, they had the best price at the time and offered free shipping but YMMV.
