replacing the pickups with white ones is easy enough(although i would be more concerned with the type of pickup rather than just the colour)
and adding a pickgaurd is not too much trouble
any
guitar shop will have a white pup selector cap it will cost less than $3
but as for the gorilla grip and inlay work that could be quite expensive.
and yes you will need to refinish atleast around the grip cause the wood is only painted on the surface,
so unless you want the grip to be bare you will need to refinish
