Rives Audio, F. Alton Everest and Jon Risch's DIY acoustic treatments ought to get you started with good info.
Be careful when trying to build / treat a room. It is possible to use materials that are non-linear across the frequency range. As such, it is possible to create more problems than what you started off with. This could be due to introducing materials that absorb / damp some specific frequencies while increasing reflections in other frequency ranges, etc... While "non-linear absorption" CAN be a "good thing" if properly applied, even some "audiophile approved" products do this without making you aware of it. Spend the money on at least one of Everest's books and read / learn what you can on the web and you'll end up dollars and hours ahead in the long run. Sean
