Important stuff...like HDTV

Anyone got a clue about it?
I just got an Onkyo Receiver and LCD projection HDTV, as well as Cox HD Digital Cable. Can anyone lend some insight on how to connect this shit together? I also have XBox.
At the moment...it looks like I am going to go component video to the HDTV from the reciever, and component video from the xbox and cable box to the receiver. I am also pondering going optical from the xbox and cable box to the receiver. Am I barking up the right tree? We're talking about much $$$ for the friggin' cables, so I want to be sure I am right.
