How do I sharpen it?


Many ways: various stones, or Scary Sharp (wet & dry stuck to glass, web
search for it) is probably your best bet.

I have got an angle grinder,


Don't use any sort of powered metalworking grinder to sharpen a chisel -
you'll overheat it and destroy the temper. If you were in a position to
do this, you'd have other and better options available to you. Powered
chisel grinders are too expensive, so go with the Scary Sharp.


What about nicks in the edge? Can wet & dry paper remove enough metal?
What grit?


==================================
Start with emery cloth on a flat surface. Hold the chisel vertically as if
holding a pen and work it until the nicks are gone. Continue with the
emery cloth at the normal sharpening angle until you've got a basic
cutting edge and finish with wet & dry or standard oil stone. The emery
cloth is a bit drastic but it does get rid of nicks and doesn't carry the
risk of angle grinder treatment.
