First off, once the audio is clipped or distorted, nothing is going to bring it back to "good".
However, there are a few things that you can do to make it less "bad". If you have (or can get) any audio processing programs, it's time to read up on filtering... I use BIAS Peak 5 and Soundsoap 2 in addition to Soundtrack Pro. If you're on FCP4, there are some audio filters included, but the environment isn't as conducive to audio work.
Start by carefully reviewing the audio to see which tracks are the clearest. Sometimes this is just one channel. If the wireless was clear (but broken) you may be able to use parts.
The next step is to try to filter out the most offensive noise. Settle up to the fact that the audio's blown, at this point, you're going for clarity. Correctly using SoundSoap, an equalizer, or some of the high-pass and low-pass filters can cut down the offending noise. It will also usually "thin out' the voice(s) you want to save.
If you can find a single good channel, you can split it off in FCP (unlink from the video with Apple + L, then split the stereo tracks with Option + L) and double up the good track by double clicking it into the Viewer, then dragging the good track back to the timeline to overwrite the bad track. Make sure to set the pan correctly on the repaired track and Option + L can then be used re-link the tracks.
In the end, what you'll want to do is carefully mix the best fix(es) back with at least one of the bad tracks to restore a little bit of the lost frequencies. If you find the audio mixer a little tricky to use in real-time, you can always set your velels manually in the timeline or the viewer.
There's more, but that's how to start...
Good Luck
