Welcome to the IMAC world. Looks like you got some really good advice here. I dont have a lot to add but here are a few of the things that I believe are most important.

1. Get a good airplane, but it doesnt have to be a full blown IMAC ship that can win in Unlimited class either. That will come in time. Read good articles on flight trimming and set up. A truly exellent flying airplane is 50% design and 50% set-up and trimming.
DONT SET IT UP TAILHEAVY. A properly balanced model will not fly hands off when inverted. If it does, its tailheavy and will never be a competitive airplane.

2. If at all possible, find a current IMAC pilot to practice with. You can learn a lot.

3. DONT expect to win at first. Never skip a contest because you dont feel ready. Unless your airplane has a mechanical problem that will keep it from flying safely, go and compete.
As a rule, one contest flight is worth 25 practice flights. You cant replace contest experience and you cant learn and grow much without it.

4. Attend one of the IMAC Judging seminars. You will learn a TON and make lots of new friends.

5. Never be afraid to ask questions. Dont ever go to a contest and feel like you can approach the best pilots on the field, even if they are "pro" pilots. Just about all are more than willing to help you out.

6. Always, always, always keep it fun. Competition is great but never let it become work.
