If the System Preference pane's Tracking Speed ain't fast enough for ya, you can hack it to a faster setting than the slider allows. Use these Terminal commands:

For mouse (the default max is 3.0):
defaults write -g com.apple.mouse.scaling (insert number here)

For trackpad (the default max is 1.5):
defaults write -g com.apple.trackpad.scaling (insert number here)

...then log out and login again. Any subsequent change made in the Keyboard and Mouse System Preference pane will override your hack and return to normal.

You might also try iMouseFix, which allows control of just the acceleration:
