1)  What's the best procedure for using Audio Snap to move transients in a midi clip?
2)  What's the difference between long and short transient markers?
3)  Some of the transients can only be moved in one direction and not the other...why?

That's a trick question, right? MIDI clips don't have transients. 
 
But if you're asking about audio clips, the answer is "It depends on what you're goal is".
 

2)  What's the difference between long and short transient markers?

 
Marker length is supposed to be proportional to audio amplitude, but sometimes it's not so accurate.
 

3)  Some of the transients can only be moved in one direction and not the other...why?

Could be a bug, or it could be that there's a hidden transient marker (possibly superfluous) so nearby that you can't move the marker much at all without exceeding stretch limits (25% to 400%); try zooming in to see any markers that might not be appearing at the current zoom level.

OK, to be more specific, I've recorded some soft synth piano chords that are not perfectly in time and I'd like to fix that.  Other than re-recording, what's the best way?

I wouldn't use Audiosnap for this.
Midi is easy. In Piano roll view, hit Q and input the degree of quantizing.
 

If that's too rigid a solution, also in PRV you can click on the offending data and physically move it.

Ya know, while driving home from work I was thinking that might be something that could be done in PRV.  I never use PRV so...this will be a learning experiencing for me.

Quantizing can be done anywhere so long as the MIDI clip is selected, but the PRV is the best place to see the result. I recommend quantizing by a percentage (something in the 50-80% range usually does the trick - tighter for drums, looser for other parts.), and quantize only start times, not durations.
 
 

WaaaHooo!   Thanks guys ... PRV did the trick!  I'm not a keyboard player so my timing is off on the keys I lay down.  This will make a dramatic improvement.  This place can be such a great resource!

There are a few good videos on PRV editing.
It has several clever, simple but effective editing functions.
I find it very flexible, fast and intuitive.

Will do, thanks for the tip.  This is the site that keeps giving.
