1: PS2 with Component Cable worth it? 2: How can I get audio from my laptop onto TV?

Hello people, I was referred to this forum by someone on another forum and I must say this is brilliant. UK based with a lot of people who know their stuff in the AV field I look foward to using these forums as a source for help about my TV and future TV's.

Ok onto the questions.
1: Is a PS2 with component video connection that much better quality than composite video?

2: My Laptop has a 3.5mm Stereo Mini Jack Output. Which cable would I need to get the audio onto my new TV?

Also here is the TV I plan on buying:

Thanks in advanced for the help
