Well, it is sounds like an easy task as long as you know what you are doing.
The "short" way seems to me,
at startup,
creating a .cmd (or maybe an .exe , maybe autoit/exe .. ) to kill explorer, start ie/chrome (maybe also delete taskmanager and cmd and run box to avoid users .... )
Hint:
You can easly create a plugin with startup option with "Plugin Creator" at Utils\"PC Packed"

"Long" way is to create a plugin that do things ready for your goals, this requires your learning some script language and inspecting how things work....
I hope above helps,
In all way, good luck to you
