Custom Hooks?

[BigJohnny]

I have read in a few places that it is possible to create your own custom hooks in (almost) whatever location you want.

Well, What is the easiest way to go about creating custom hooks I can use?

And is it possible to create hooks in PHP files that arent vBulletin defaults?

Like if i have a mod that has PHP files on the server, could i create hooks in those files so I could modify the mod, without actually modifying it?

Yep, you can -- off hand I know of one modification that does this: ecDownloads. Take a look in the Articles forum, there are at least two articles about creating custom hooks.
