Sort of Quantizing Audio?

Goal: Create a click track with guitar and vocal, as a guide track for drummer/bassist to lay down the rhythm section for a song.
 
Challenge:  I recorded a guitar "skank" part for a ska song, playing with Sonar's metronome. I have fairly good timing, but those times I was contemplating global warming or whether I would date Carly Fiorina under duress, my timing was understandably thrown off. I'd like to fix that.
 
I've been editing and have a few questions regarding best practices. Of course, I want the part to remain human. If played perfectly robotic, the skanks would start at 480 ticks in each measure.
 
Questions: 
A.  How far off the 480 is "reasonable" to stray, to be human but not too off?
 
B.  Is there a rule of thumb other than "if it feels good"?
 
C.  Other than re-recording the track, is there a way to edit this other than painstakingly checking and moving every one of the 97 skanks that are off?

Ken, thanks for pointing me in the right direction. I've never learned AudioSnap but will dive in on Friday. Just reviewed the online documentation on it and it definitely has the potential to do what I need to do, way more efficiently than I was doing it.
 
While not new to Sonar, I've never had to dive in too deeply, but this is an essential tool for which I'm already grateful, in advance.
 
Will report back.

Thanks, guys. Very helpful. My first foray into audiosnam was...a courageous if not flawed attempt. What I found was that in this ska skank track, I played the skank chord AND a clicky rhythmic thing opposite the skank while recording. But the audiosnap kept going to the clicky thing even though it was a lower level, and it wouldn't align on the chord played.
 
Couldn't figure out how to get the settings to adjust to that. Tried so many, experimenting with a lot of options, each one a more humerous result than the next. You know how interesting a ska track sounds with all of the skanks stacked on top of each other? I do! Hey, at least it was in time.
 
Then something I did added injury to insult... the project got soooooo sluggish. Saves were getting longer in time. Shut down sonar, rebooted, but when opening the project again, got this error message: http://screencast.com/t/bnoyeWFsrC   Ended up having to export all the tracks, create a new project file, and import the wav files.
 
Bluzdog, that video's helpful but blurry, did give me some clues. Downloaded some groove3 trainings too.
 
Kevinwal, I look forward to playing with that too, and first will learn audiosnap as it appears to be a primary tool for many things.
 
Craig, thank you, am heading to those links to get a clue!

That is a typical message, when a Region fx has not been rendered. Maybe you did not remove it, and added new ones, causing your project to slow down?
All the best.

Very possible, as by the time that had happened I had done so many experiments gone wrong, I think Sonar threw up it's hands and said, "Go study some more and stop wasting my time!"
