I'm installing backerboard for tile in my shower and it is an old house with plaster walls. The plaster is quite a bit thicker than the backer board. Should I shim the backer board or just try to level it w/ compound. If I should level it, what should I use. Thanks in advance for any input.

I'd use shims. They sell thick pieces of cardstock that is 1.5 inches wide by 8' long at most supply stores made just for shimming wallboard products. You can staple it in place then nail or screw the backer board on top to the studs.

Don't forget to install a vapor barrier behind the backerboard in those wet areas. It should run down over the tile flange of the tub or over the liner if in a shower.

What has been said thus far is correct. Ideally you would want all surfaces to be on the same plane. If you choose not to bring it up to the same level then you have the option to butt tile to the edge of the plaster. If you choose to do that make sure you have adequate support behind the wall to prevent flexing at the juncture.

Hey, wait a minute.

This is awkward, but...
