my advice would be to spectrum analyse absolutely all the parts of your track, make a table of frequencies, and look for conflicts.
you'll be supprised at how much action there'll be in the sub 400 Hz area, if you have say more than two parts with a fairly dominant spike at around the same frequency, try changing the notes of the parts or use HP filter on some parts and spread the spectrum out.
as a rule of thumb, always assume that the fundamental frequency of almost any sound is a lot lower than you think it is, ( this is from my own experience, its not something i've ever read about, so it maybe it wont apply to you )
eg mid range sounds which you might think are in the 500 - 800 Hz area, probably have a fundamental in the high bass 150 - 250 Hz or low mid zones, but when you're cleaning up your bass end, you're probably only listening to the bass sounds.
I would agree with this. Some sounds are really 'messy' and have all sorts of frequencies that you didn't want specifically from the sound.
FM I found especially bad. But unfortunately filtering too much can change the tone or impact. It's a delicate balancing act I guess. (in some software synths you can have lots of options for filtering..sometimes you can use a high pass or low pass filter that is controlled by an envelope on the synth... you can sometimes have ncier control over sounds with this than using a regular eq)
I also had some nice results from heavily boosting a certain area on the master with an eq and listening back then.
Clashes and other nasty bits will jump out.
