Your situation is very similar to mine in that i bought a lake 4 years ago with some of the same issues. Have Bob Lusk or some of the other experts advise you, but several things I noticed. First, the aggressive removal of all bass under 14 inches will do wonders. Next, I seems the number of bluegill (100) you put in is way too low for the size pond you have. I removed all crappie I caught and also removed some of the larger catfish as they compete with the bass for table fare. I strongly suggest protein feeder(s) for the bluegill. Of course, a professional analysis of your lake by shocking would be a good starting point. Good luck and have fun.
