I'm doing my first meet next weekend, and I couldn't be more excited. I committed to do the meet in November, and since then, my training has taken on a whole new meaning. I know that I probably won't win, but I know that I want to do my best.
I've also been told that the environment at most meets is a huge bonus - that it's very positive, educational and addictive. I've run a few half-marathons, and I know that the environment there was like that - and it makes all of the training worth it.
Don't worry about your weights, they're good. The only thing that I'd suggest is to do some work on some singles (if you aren't already), just so that you're prepared for the meet. It looks like you've built up a great foundation of strength.
