Well when playing around with the audio-framerate (although audio really doesn't have fps, but I'll stick to the term anyway), and you make it play faster (like when converting to 24fps for using like the Read ErMaC & AbsoluteDestiny's Friendly AMV Guides states), the audio is supposed to be a little noisier, or higher pitched (if that's the right word for it). Because when you take a waveform, and make it "shorter", it will just sound higher...
So there shouldn't be any problem when you're working with this audio file in premiere. When you eventually switch back to the 23.xxx fps, and you use your normal audio file all should be up-sync.
Hope this was of any help to ya!
