i'm new to this too but try this:
in multitrack view, highlight only the waveform (beginning of first sound to end of last sound) in track X
right-click and then left-click adjust boundaries
now you have an unmoved, "truncated" wav
(do that with as many tracks as you need to)
now right-click and drag that sucker back and forth until it matches up with the other tracks
oh yeah, the closer you zoom in horizontally, the smaller the intervals of movement when you drag the wav
hope that helps
