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?
