I would let it harden up first. It can be done when still soft, but if you've never done it before, wait for it to harden. There will be less chance of damage to it when its good and hard.
Oh, and 1000 grit should be good, but if your worried again, start with 1500. To polish you should be able to rub it out by hand with compound and a soft cloth. Polisher will be faster, but again, only if you have one and know how to use it.
