RE: How to change speed of an audio track
There are algorithms to alter the speed of sounds without altering pitch however these introduce distortion and artifacts in the sound and I recommend against using them.  It's probably better to either just shift the pitch or change the framerate of the video.

However Sound Forge's Time Stretch feature does seem to be one of the best I've seen (defects are still noticeable, but if it's not a big issue, it may be acceptable).  Haven't tried other suggestions ere though.
