Here's my second shot at adding some manual filters. I went on the assumption that my limit will be 12 bands of EQ, because if I were to purchase something, it would likely be the Behringer DSP1124:

I would be careful using a EQ filter to boost. If it really does boost you will lose headroom, but often you won't be able to actually boost a null.

I doubt you would ever need 12 bands. Take a look at this great post from HTS.

He shows how to reduce the number of filters needed (and which are not even really needed). I've read through a few peoples threads and they start out using a lot of bands, but in the end they get the best sound with only a few. Also he talks about setting up the target curve for the best starting point of adding filters.

Also, take a look at his discussion of house curves. I used a house curve, but with limited EQ bands I didn't try for the hard-knee house curve he talks about. It is an interesting read.
