Welcome to ePlaya, Scamp! Love your avatar! That says quite a lot about you right there. And you introduced yourself well in writing also.
The general-purpose advice is to avoid over-committing the first year. But some folks have pulled off great theme camps and big art that way. I remember feeling fairly overwhelmed my first year. Then I pulled off a rather good theme camp with 25 people the second year.
Either way, it is
fun, and it sounds like you are "one of us".
You should read the First-Timer information, specially the entire Survival Guide, and you should sign up for the Jack Rabbit Speaks newsletter. And participate in discussions here on the boards.
