In galoot time, I guess I might be a little early; but in real time I 
apologize for being so slow to return thanks to all for their sage 
advice on these subjects.

I decided to leave the guitar frets until I could visit a pro to see if 
the action on the Yamaha can be improved.

I did sharpen the scissors.  They cut better, anyway; but I don't know 
that they are properly sharp, yet.  I found a copy of Scissors Sam Says 
be Sharp at abebooks.com for a not totally exorbitant price.  I expect 
to see it arrive in the mail next week.  With it in hand, I might have 
another go at the scissors.

In any case, thanks to all who responded to my queries.  The information 
served to prevent me making things worse. (I know that never happens to 
any of you :)  )
