Turntable Set-up Resources - Help


I am a vinyl newbie that has just ordered his first turntable - a Rega P25 w/ Grado Sonata. I have zero experience and only basic understanding of what I'm getting in to (but, I have been bitten hard by the vinyl bug and am looking forward to learning as I go). Two questions:

1) A good friend of mine has a copy of the TELARC Omnidisc that I plan to use when setting up my system - does anyone know where to look to find one to purchase?
2) What other instructional set-up resources are out there and how do I find them?

Thanks.

The audioasylum.com FAQ helped a lot with my setup. And Chazzbo gave good advice: a mirrored protractor is quite a bit better than a paper one. I would add that if you do not have one, you should get a pretty decent level. I'm not postive, but i think the omnidisc is out of print.
If you have a Linn Casey (www.extremephono.com) has a web site and is into it.Or ask him here loking up extremephono.
