Ok this is probably easily answered but i cant find anything that tells me exactly what I want to know.

I understand that HDMI will transfer Audio and Video over a single wire but my question is this
If I plug the HDMI cable into my Motherboard and the other HDMI plug into the LCD tv, will it just pull Audio fom the PC's sound card without a cable running from the sound card to the TV?

And also if your sound card, onboard or otherwise has a optical out, can this plug into the TV for sound or is this intended to hook into a Receiver?

Yes, HDMI will carry sound to your TV without additional cables.

If your TV has optical-in, then yes you can plug the optical into the TV. If your TV has HDMI then you don't need to do this. If you want surround sound, then you should connect the optical to the receiver.
 
I don't believe all motherboards support audio over HDMI. You should check that on the makers site. If not then use the SPDIF digital audio out (coax or optical) to your surround sound receiver and/ or the analog stereo out to the TV. There is no disadvantage in performance.
