I just went from a 100 mm stem to a 70 mm stem on my Tarmac and I really like that I shortened it. But which ever you can find inexpensively to try will give you an answer of what to spend real money on.

One hint as to whether being able to move the saddle forward more is whether you slide forward too far when you pedal harder. Though that can also be other things, like too long a stem or saddle tilt. But if those things seem already within reason based on your elbow bend and what looks right for your saddle angle, then maybe your saddle should be moved forward.
