Turbo boost questions, and what is "detonation"?

I was reading an earlier posting by WASSAB and he mentioned that he's running about 26 psi of boost, but is getting detonation.
Here's a couple of questions: 1) How much PSI corresponds with the gauge markings (ie - between yellow and red, full red)?
2) What are the symptoms of detonation?
I've just finished tweaking my engine and can peg the red, but I'm afraid of sustaining that (I've got a manual grange boost valve, so the APC doesn't regulate boost pressure). Am I justified to be worried or can the engine and transmission handle that kind of sustained boost?
Thanks
Todd A.
