Try shooting in manual mode next time. Keep the aperture to the lowest number you have for those lenses. Then bump the ISO way up! I see many of those shots are at iso320, 200, etc. Should be no less than 800, and you might as well try some at 1600 to see how well it handles the noise. My 40D is always on 1600 for concerts. Other than that, great start, keep it up!
