How come, if you have the prop off, you would push the bearing forward and cut it off the shaft with a grinder rather than simply push it aft and let it slip off the shaft? That's where the new one goes on....

I think the usual way to replace the cutlass bearing is to remove the prop and leave the shaft in place. Use a pusher to push the cutlass bearing forward on the shaft and out of the strut.  Then use and angle grinder to cut the cutlass bearing length wise and remove it from the shaft.  The same pusher can be used to set the new cutlass bearing in place in the strut and then reinstall the prop.  You can get a special made tool or you can fabricate one yourself whichever is easier.  A puller is required to remove the prop.
With that said, I am not sure you need to replace the cutlass bearing if the play is only 20 thou, doesn’t seem like a lot of play to be but I never checked a cutlass bearing by measurement, more by the feel of the prop shaft as I push it hard from side to side.  You should easily be able to decide if the bearing is in need of replacement by doing that.

Hi guys and  gals
I have my 34 on the hard doing bottom paint and 2 thru hulls. My cuttless bearing has probably about 20 thousand's play and there is lots of  meat left in the bearing itself. I asked the machanic at the marina how much to replace it and he said atleast 2 hours at 100 per hour and a hundred for the bearing. He also said the bearing may not  come out and then of course we would have to pull the shaft and that would be much more. So im going to put it off till next haul out in 2 years. My question is whats the  chances that i won't be able to get it out with a puller and have to pull the shaft. Which I believe means pulling the rudder as well.
