Probably, but if the orange peel is bad it might be a good idea.
As for colorsanding after, depends what kind of finish you are looking for. Are you looking for a super flat, perfect show finish or just a very nice paint job?
If you want it dead perfect flat, start with 600 and work your way up.
I did mine and was able to just use 1500/ 2000 then buff... but it all depends on what you are looking for. With 6 coats of clear you will have enough material to do what you want.
