I deleted the smog pump and associated AIR system crap 5 years ago. No additional smell, and it's passed emissions every two years since. RI still does sniffer tests on OBD1 vehicles. (yay)
From what I understand, the AIR system is only operable for the first few minutes of run time on a cold engine. If you want to delete it, have at it.
Back to the gasket issue... I've tried a few different types, Remflex, Percy's, and now Fel-Pro. So far, the Fel-Pro gaskets have been the least problematic in terms of longevity, and not having to re-torque bolts after every 20 mile trip.
Summit sells a set of shorty headers with the EGR tube fitting on passenger side header, but I haven't seen any with the AIR fittings in them. That's what I have on mine and they've been great.

I didn't do an EGR delete, simply because it'd fail a visual inspection here in RI. The tube fitting is a pipe thread, I think, so you should be able to find a plug at your local hardware store.
There are bypass pulleys available, but I didn't use one, so I can't provide any info on that.
If you leave the check valves in place that are in the pipes that go to the exhaust pipes, you can leave the air tubes in place. Since you're having exhaust work done anyway, either have that shop cut the tubes and crimp/weld them, or cut off flush with exhaust pipe and weld a patch over the holes.
I never bothered painting my headers, and they've seen 3 New England (think salt soup) winters with no issues.
