The drivertest.exe isn't really a valid test imo. If it runs fine at 35K but not 45K, then leave it at 35K.
I'd leave the pulse widths at 5us if it's running fine. Lowering them won't gain you anything, and may not run as well.
450ipm is pretty fast, especially with those rather small motors. By lowering the velocity, you may be able to increase the accel. This may be desirable when you start cutting parts. You'll most likely be running Mach3 in CV mode, and higher accelerations will allow the machine to follow the toolpaths more accurately around corners. However, if the accel is too high, you may run into issues with the machine rigidity, as high acceleration can cause rather violent direction changes.
Sounds like you have it set up pretty good. You just might want to play with the accel velocity numbers and find out what works best for the work you'll be doing.
