What if I used washers with an ID big enough to go over the sleeve, that way I cound take up the slack with them and when I tightened the bolts, they would squish, or preload if you will, the poly bushings...

I can send you some, but any decent hardware store will have them too.
As far as the gap, the sleeve is pressed into the bushing, it's not going to move around if the bushing isn't bottomed out. It's fine.
