On your egr valve I was thinking actually that they made an EGR Valve eliminator. It might not be a total waste of time to look and see if you can run across one.
On the coolant lines for the upper Id leave them open. If nothing else it's going to keep the temp of the intake cooler which is supposed to make more HP or something like that according to all the aftermarket cooling items.
On your bolt I'm with paul I've never seen a torx bolt in the intake either. Just a suggestion which you probably already thought of is replacing it with a normal bolt so theyre all the same socket if you have to take it back apart.
If you don't have one to use try your local hardware store. Autozone was going to charge me over a buck a bolt for the ones in the center of my intake.
Hardware store had them for like 56 cents a bolt. I saved near a buck a bolt just by using the hardware store items. Since its not a high pressure area at the moment I don't think it should make that big of a difference that they're not auto bolts. Just ideas to try and help out after all the help you've gave me with my wiring.
