If I was you, I'd learn different openings, especially for black. Check out this rather informative thread (especially the second post) regarding good black openings for lower rated players. A rock solid opening leads to a decent middle game.
Spending some time with the tactics trainer would get you to see the traps laid for you as well as help you lay a couple yourself.

This is the first tournament that I played without my school chess club, and my first individual USCF rated tournament. I was part of a three way tie for first in my group of five people, scoring 2/3.
Any analysis of the games would be appreciated, but more importantly I'm wondering if anyone can tell me what I need to do to improve; that is, what parts of my game are weakest and how can I work on them? I would really appreciate any advice you can offer.
I've fully annotated the games, and analysed parts with the chess engine Crafty.
I was happy with how I played in round 1, I don't think I made any blunders, but a few mistakes and inaccuracies.
I thought that I played a good middlegame in round two, but major mistakes in the opening and endgame lost the game for me.
My last game was very poorly played from both sides, my opponent and I both missed some very elementary stuff.
Thanks for any advice you can give!
