This website is fantastic. I work with acousticians on studios and this is exactly what the big boys are doing. I'm working on one project out in NJ and the client is paying a fair amount for this same information (and a project mgr!). When I built my studio this page was my bible.
Also, you always want to reference as many systems as possible. Become familiar with your monitors. Listen to commercially done music that you know very very well and listen to how the bass sounds compared to the low mids compared to the mids to the highs. How are the dynamics? Familiarizing yourself with your monitors in the acoustic environment they're in is the most important thing you can do. You can have great monitors in a crap space and end up with a mix that doesn't translate very well at all.
