Scott, I'm having trouble understanding what you want. Your codes imply that the EGR isn't hooked up, or if it is, the hose is blocked. The other codes are for your smog pump. Is it installed and functioning?
As far as a vacuum leak, if it's hard to verify, use a propane torch on high, no flame, and point it around the suspected gasket failure. If the idle improves, you found it.
If there's more, please explain it to me better. Pretend I'm 9 years old.
Take care,
~Chris
