I'd say leave it if you aren't having any problems with it.
However, if you really want to pull the whole thing off, you can pull the air pump and all that tubing attached to it, plug all the vaccum lines that were leading to it's various portions, remove the metal tubing accross the back of the heads and plug the holes with inserts, and plug the tube that comes off the x or h pipe and leads to the smog pump system. You'll need a short belt to match the pulleys you have left, mine was 76 1/2" I think. The tensioner will have to pulled way the hell up so it doesn't interfere with the water pump pulley. I think that's everything....
oh yeah, pray you don't ever have to put it back on.
