I am still pretty disappointed with how we faired but I just have to chalk it up to a learning experience. I had no idea what I was getting into but I enjoyed it.
Enjoying the experience is the main thing. Everything else will come with time and experience. Set reasonable goals for yourself for each competition (e.g., finish in the top 50% and get a call, etc.) and increase you goals as you go. While it is certainly possible to hit a home run in your first at bat, it's more likely that you'll strike out, bu if you learn from the experience and improve each time you'll be up there accepting a trophy and check soon enough.
