 This are my advice as well. Especially use the profiler and change your
high level algorithms. You will find a lot with hidden quadratic behavaviour
which slow down your program when it comes to high volume.

Psyco will generally speed up 2. This is fine (I use it!) but not a break
through. There may be cases where it performs better.

A bottleneck can be Tkinter. Use something different then (Qt, wx)..
