Canon eos 450D. Billiard game photos.

Hey there, guys! 

I'm new @ this forum, so I hope someone could help me figure out how to use my camera right. ^^

I got Canon EOS 450D, and my friends asked me to go with them to billiard game and take a pictures there.. But, sadly, I don't know how to put right settings for capturing something like that, because billiard clubs are always dark and lamps are only on the tables..So that all looks like :

So.. Can someone, please, tell me how to set my camera for something like that? ( ISO / F/--- / etc ^^ )
