Seconding Beat's suggestion for trying out a "frequency sweep" approach as well - this one is also very good for equalization ear training, as it makes you remember how a particular frequency band sounds on different instruments when you "overemphasize" it (provided you do this in an organized and regular fashion (I would start with "standard" octave spectrum divison (63-125-250-500-1k-2k-4k-8k-16k)).
EQ presets: honestly, I don't have any. I am so used to doing EQing completely dependent on the sound of every inidividual project/mix that, if and when I use any, these are almost always Vienna Suite EQ Factory Presets as good starting points.
