Vacuum Line Deletion?

[Bullz_EyE]

I broke a nipple of that vacuum sensor thing on the water neck. In this picture this person just dosent use it at all, then he uses it as a water temp sensor bung. He also has one hose on his throttle body deleted. Then later he just deletes both on the throttle body by looping it. There's a bigger line too and it's been circled. There is also one that I didn't circle and just noticed. It's on the end of the intake manifold (left of throttle body, towards front of vehicle). Obviously there are some things you can do without.

I want to know what to know what those systems he bypassed are. Anybody have a clue about the one that I broke? I'd rather bypass than spend money to replace if it's not critical to performance.
