Installed new ring and pinion last weekend, and the wear pattern is bad....
How can I remove the bearing off the pinion? I need to shim the bearing.
This is a 8.25" rear.

Wouldn't the shims have to go behind the 'bigger' race? If so, the shims in the kit were way too small...

OK, everywhere I look I see shims being placed on the pinion itself. I would much prefer punching out the race and doing it that way but I'm kind of confused based on the size of the shims...

That is correct. There is a special tool used to remove the pinion bearing pictured in the factory service manual, looking much like the one John posted above.

When I rebuilt my 8.25 there were no shims between the bearing and the pinion and there were (3) between the race and the case. The master kit I got also had shims for the pinion. I lucked out and two of the ones behind the race got mine pinion where it needed to be so I never had to go looking for the larger shims.
BTW, I mocked up mine with some gauge blocks and a drop indicator to set it for the depth engraved onto the end of the new pinion. I was within 0.002" and when I put it together the pattern was perfect. Also, a lot of pinions will have another number engraved onto the bottom like +.004 or -.002. If the existing one has a similar number you take the difference and adjust the shim pack by that much and you will be where you need to be.

OK. Took pinion out and had a local shop pull both bearings on the old pinion and new. Then I made a 'slip-on' bearing out of the old one, good thing I did too. It took 4 times to get a pattern that I liked.
Now a new problem has developed: I can't get the crush sleeve to crush! I am using a brand new CP Earthquake impact (625 ft lbs). There is about 20-30 thousanths(sp) of in and out play... so I'm guesing that the sleeve isn't crushing.
Any ideas/tricks?

It's a bad idea to use an impact on a crush sleeve pinion nut, too easy to overtorque and ruin the crush sleeve. Just use a cheater bar and take the nut down slowly.
