Plugs, wires, and ignition for N2O.

My parents are buying me a nitrous kit for graduation. Its time to put that 9" rear and clutch to good use by spraying out of the hole. Soon I will be installing the usual bolt-ons (CAI, LT's, Y-pipe) and then getting the car tuned for N20. While I am doing the LT's, I figure it would be a good idea to upgrade to nitrous friendly plugs and wires.

First off, I hear people mention OTVC wires and I have no idea what the hell that is, so if someone could please explain that I would appreciate it. Second, since I will be running nitrous I will need a colder plug (at least thats what I hear tell). I know that a common plug for the LT1 are NGK TR55's. I also hear talk about copper and irridium plugs as well (Like I know what the differences/benefits/disadvanteges of those are ). Some people run AC Delco plugs and something else as well.

If I'm not mistaken the most common sizes of wires a 8, 8.5, and 9mm wires. Which should I get and why? Which brands also? I know that the common ones are MSD, Taylor, and Accel. I also know that some people install plugs and wires and then burn holes in their wires in 2 days, I'd like to avoid that (obviously).

Will I need and ignition like the MSD 6AL or something along those lines? I believe that I can run nitrous without an ignition, but would it be wise to upgrade?

Finally, it is a long ways away but the eventual plan is to pull the motor, forge it, and spray the piss out of it, so if I can get parts now that will be good then it will help.

OTVC stands for over the valve cover.
I use NGK TR6 plugs.
You will need a MSD6A ignition box.
I use MSD 8.5 mm wires.

also if you plan on juicing more then 100hp shot, go with an ignition with build in timing retard that can be triggered when your spraying.

The mallory 685 is a nice unit that offers timing retard and a window switch all in one box.

Exactly, a very good bang for the buck box. I would also go with the NGK TR-6 plugs as mentioned above. A bottle heater and fuel pressure safety switch would also be good ideas as well.
