Regarding your specific questions:
Ideal VPIP obv depends on 6-max, FR or HU - 6-max the concensus appears to be somewhere between 25 and 40.
In position, and HU, you should be c-betting something like 95%.
Hands to raise in position: a lot.
Sorry for the attitude (I'm really not) but this kinda stuff has been covered to death. If you need help finding it,
this thread is useful.
