As for your main seal issue; I'm assuming your crank is scored pretty bad? You can shim behind the seal a little when you replace it, and this will make it run in a slightly different spot on the crank.
I've read
here that for the oil pump you can add or remove a washer to adjust the oil pump pressure.
As for the crank. It wasn't leaking out of the rear main seal, it was leaking out the oil pump side. I have 2 blocks and 2 cranks, so I'm rebuilding a different block and crank.
