Also, you might consider raising your ASA/ISO to 400 or 800 and see if that helps. This may introduce a little grain into your pics but you can reduce the effects of the grain with a program like Noise Ninja.

I love my "IS" lens and in your situation....it would be the perfect tool for what your doing
