Here is the registry info for the softkeys:
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\HTC\Manila]
"IsWM6.5"=dword:00000001
"HomeRSKText"="Camera"
"HomeRSKPath"="\\Windows\\camera.exe"
"HomeLSKText"="Contacts"
"HomeLSKPath"="\\Windows\\Start Menu\\Programs\\Productivity\\Contacts.lnk"
As far as removing them, you can install a program called "DoNothing" that basically creates an executable file that does... nothing. I can't seem to find it though. Once you have it installed, you can direct the softkeys to the .exe, and replace the text with whatever you want.
