As regards to a complete script, I find that SACNR's script (Blacklite) is pretty nice. It's not efficient now, it lags somewhat, but given the creation date and the resources available then, it is pretty cool.

These are the guys that come first to my mind regarding those aspects, and I've learned from them
I hope I never become the 'best' scripter because I'm sure the satiety would kill my learning curve!

Thanks!
