Sorry, I know how you must feel, but that seemed like a likelyhood 
given your other problems.

The thing on the bottom of the dist is called the drive dog. It is 
supposed to be loose & wiggly, so this sounds normal. The 2 drive 
dogs should be nice and square, as should the groove in the drive 
gear that they mate to.

It might move a little, but 1/32" shouldn't make any difference. The 
drive dogs are about 3/16-1/4" tall, and should be nearly fully 
engaged in the drive gear.

You got it right.

I suppose it could be the starter. Or any number of other things. 
Did you verify that both washers were properly in place under the 
dist drive gear before you reinstalled the drive gear?
