sadly there is no one size fits all solution to eq'ing - if there was we could simply write a program or app to do it and never have to worry about it again
every track has its own demands and needs for eq and mix levels so every track has to be treated as a new adventure
the best advice we can give you in the one size fits all category set your Q to be as narrow as possible (effectively a notch filter), set your boost or cut to max and then sweep the frequency until you find the spot that needs work, then adjust both Q (bandwidth) and boost/cut until it is subtle rather in-yo-face (unless you like that sort of thing). repeat for each freq that needs work until problems are solved
