Welcome Mike! I started USPSA and IDPA last May. Great fun! I'm still having similar problems, but I can tell I'm getting better. I'll be 64 in October, so I'm pretty durn slow. My hits are,.... well getting better.
You should purchase from our host here "Practical Shooting, Beyond Fundamentals". Check out his store, he also has some great videos for purchase.
Good Luck,
A.T.
