What you want to do is use udev to write a separate rule for the TPoint 
and TPad. Then, set up 2 different mice in xorg.conf (instead of 
/dev/input/mice). Then, configure as you wish. Eg you can map the button 
1,2,3 presses to some non-existent buttons.

For scrolling, are you aware of EmulateWheel?  xorg.conf:

Option "Device" "/dev/psaux"
Option "EmulateWheel" "on"          #Button 2 => emulated scroll wheel.
Option "EmulateWheelButton" "2"
Option "EmulateWheelTimeout" "200"
Option "XAxisMapping" "6 7"         #EmulatedWheel vertical/horizontal 
pointer motion causes fake button 4,5 or 6,7 presses.
Option "YAxisMapping" "4 5"
