You shouldn't look at other peoples threads. Start your own, providing the information requested in the stickied thread in that forum.

Yeah, but again, I'm not just looking for my server to optimized. I'm looking for my forum to be optimized. Again, if I said that my server was optimized so that it was scoring above average for servers with the same hardware, it would not matter at all if another forum administrator had optimized his forum (plugins, scheduled tasks, cache, etc.) better than me. He would have the faster, better performing forum. It's really surprising to me that vBulletin doesn't offer any reports or logs on forum performance. They have made it so that it doesn't take a highly technical user to admin a forum, as long as the hardware/bandwidth is always a double-digit percentage higher than it needs to be.

See above.

Have you tried running the forum in debug mode (just for you - do a search on how to do this)? That will help you find out how many queries per page, what templates aren't cached, etc. But really, if you are worried about modifications and such, only you can go through them and see what is going on and see how they may effect other modifications you have installed. And if they aren't working well together (each doing the same thing or redoing something or doing things that contradict the other or ....) then only you can go through and rewrite them just for your forum.
