Shop Air Suggestions

[ItDoRun]

I just bought me a new 2 stage 80 gallon compressor and want to plumb my air inside my shop. The compressor will be outside. Will PVC pipe work okay for the plumbing? What size should I use? Also, where can I get a decent in-line filter/regulator for it?

I plan on running the line inside the shop to the filter/regulator, then coming out to a tee and running horizontally across one wall in my shop and tying into two hose reels that will be mounted on the wall. Instead of the tee, should I get a 4 way and put a drain valve at the low point? If so I could slope the lines back to the drain valve to help keep the lines free of moisture.

Any suggestions or pictures, perhaps? Hopefully I painted a good enough picture of what I'm trying to do.
