moving all keyframes w/ one
How can I pull or push the beginning or end keyframe of a series of keyframes and have the rest compress or expand in a corresponding manner? Thanks!

Select all the keyframes.
Animation (or Right Click)>Keyframe Interpolation>Then in the Dialogue Box at the bottom change “Lock to Time” to “Rove Across Time”. You now have Roving Keyframes.
Probably a faster way (I forgot about it until I fiddled with your question) is to click the twirly on next to the Stopwatch, lets say we’re animating Position, so click the Position twirly to reveal the graph. Now the keyframes in the middle have a tiny square box with an “X” in the middle. Click on the “X” and then you have just an empty little square box underneath a Roving Keyframe.
I’m on AE6.5 so hope the graph hasn’t change as far as keyframe interpolation goes.

Select all of the keyframes that you want to compress or expand on the timeline, then hold down opt (or alt on PC) and click either the first or last keyframe (depending on which way you want ot compress/expand) and drag it on the timeline.

[yikesmikes] “You now have Roving Keyframes.”
Roving keyframes won’t keep the original animation intact, the keyframes will initially ‘rove’ so that the rate of change of the animation is continous. If you had keyframes that were very intentionally spaced for a sudden change in the rate of the animation then you’d want to avoid roving keyframes.

Yours is easier. I learn something new everyday.

yopu can also just select all the keyframes, and in the graph editor, use the bounding box to squash or expand them.
Just to make sure it;s super clear (I know it was mentioned) Roving Keyframes is a bad way to do this, because it actually changes the timing of your animation, Timing becomes based on distance between position at various keyframes – not based on the timing you used. Expanding and compressing keyframes the way either I or wuzelwazel suggest will keep the timing proportions correct.

I disagree vociferously!… Just because I miss the good old days (;
