The keyword is: Haar Measure. See for example this http://gemma.ujf.cas.cz/~brauner/files/Haar_measure.pdf" [Broken].
Sorry for the short answer, I'm in a hurry.

I passed over a discussion which shows that integrating over SU(2) is similar to that over a sphere S^3. I want a similar discussion for integration over SU(3).
Can someone please specify a reference that gives a good explanation of SU(3) (like finding generators, etc..)?
Thanks
Among other things, it discusses Euler-angle parametrization of SU(3), and the definition of an invariant volume element. Take a look at section 4 in particular.
