I agree with all of the above Chris. Just a couple of additional thoughts:
Cellulose dries very quickly but takes a long time to fully harden. For that reason leave it as long as possible before flatting down and re-coating. So for instance spray your primer coats then leave it for a week with plenty of ventilation before flatting down and re-coating. You will get less shrinkage of the paint this way. Before the final flat and polish leave it for as long as you possibly can.
Use a guide coat before flatting down: spray a very very light coat of (say) black before flatting down, flat down with a block and any low areas will show up as black marks. Fill these with cellulose putty if necessary.
Cellulose is not made by the major producers any more so the quality can vary. Watch out for any reluctance to fully harden (especially black gloss) and if so try another brand. I've no experience with Craftmaster but they seem to have a good reputation.
Treat yourself to a good quality respirator and use cellulose or "organic compounds" filters (not just dust filters). 3M do a good one.
With a bit of patience you'll get a great finish.
