I finally broke down and ordered an insert puller from Bowler's Choice (www.bowlerschoice.com).  The "Insert Grabber" seems to work pretty well at extracting fingertip inserts.  You work it down on one side of the insert, then you twist the insert remover to cut through the glue bond around the rest of the puller.  It is a handy little gadget to have, although a screwdriver, pocket knife, and bevel knife combo works pretty well too.

Hamster, even though it isn't outwardly obvious, sanding the fingerholes with the bevel sander does indeed remove some of the coverstock in the fingerholes, which can lead to the inserts fitting even looser.  I used to not get too concerned about sanding out the fingerholes, but my newest ball driller is very picky about getting the finger grips sized right, and he only buzzes out the holes in 1 to 2 second increments between sizing checks.....and, believe it or not, I can tell a difference in the 1 to 2 second sanding swipes.

As for removing the super glue residue, I prefer to use a pocket knife, a bevel knife, and I've found that the razor edge of the Insert Grabber also does a good job of slicing out the super glue.  If you want to remove all traces of the previous super glue, then you can buy super glue debonder on the market, or you can also use Acetone to soften up the super glue so that you can remove it (Acetone will dissolve super glue)....of course, be careful on where you get the Acetone, since you don't want to use it on the outer coverstock.  Also, hand sanding the immediate area of the super glue residue will also work too.
