Daniel, My understanding is (I'm definitely not a Mahematica guru) that Mathematica automatically does the biggest thing that can be done to speed up NIntegrate-- when you run NIntegrate, Mathematica automatically compiles the function to be integrated so that it will run as fast as possible. If there are any other tricks for making NIntegrate run faster, I would also like to know what they are. By the way, if you have not yet upgraded, I have found that Mathematica 5.1 performs NIntegrate at least three times faster than Mathematica 4.1 did on the functions that I have been integrating, which involve double integrals of fairly large functions.
