xbox 360 HDTV help

[Touring Remo]

Hi guys.

Firstly i apologise if this is in the wrong forum.

Wondering if anyone can help me. I have finally gone HD and bought a 720p tv, so naturally hit the switch on the cable into the xbox to hdtv and set the display settings to 720p.

If i wanted to use an HDMi cable would this make the picture any better?

Also, if i keep the original xbox lead, its got an optical audio plug in the plug (xbox end), i've also got one into the back of my tv. If i get the necessary lead, what will i gain using the normal hdtv five wires? Better sound? I havn't got surround sound if that makes any difference.

Thanks in advance.
