as far as equalizers... 30 band software EQ? Damn man, what in the world do you need that for? I mean 10 bands is too much for me; why not go with a 3-5 band parametric EQ?
As far as lossless, here is a listing of a whole load of diff lossless codecs you can check out. No comparison is going to give you all the facts, as there are tons of different "features" and "issues" with different codecs. How well they recover from errors, what kind of metadata they support, what kind of software support is available, etc etc etc. Personally I use FLAC for lossless encoding, as it recovers well from errors, is supported with every player I currently use, supports lots of metadata (including replaygain built into the codec), and it's free and open source. For "near lossless" or "effectively lossless" I use Ogg Vorbis, q8; for the same/similar reasons as above.
