the 2nd most important thing is to be patient with the lip and not try to pop to early causing you to "pre spin" or start spinning while you are still on the lip.
This is probably the hardest part for me when I learned front and back threes and when I relearned front 3 off the heels (instead of toes), I had to relearn it all over again. If you can do that and the set-up turn, you can front three. Then it's just a matter of doing it so the blind landing is easy. That part feels awesome, blind landings are sick once you start stomping them.
Good luck and have fun.
