Auctex for emacs?

[saneman]

I have just installed auctex for emacs, but should I enable something in 
 my .emacs file to make it work?

Another thing. I am used to the Latex editor Kile. In Kile when you type 
'\ref' a list of all your references pops up and when you type '\cite' a 
list of all items in the bibliography pops up. Is this kind of 
functionality available in emacs?
