Recording to Computer

Was wondering if anybody can help me out with recording from instrument to my computer. I have a Yamaha P-60, and HP Media Centre 2.8ghz 2 Gig RAM. It will be classical piano pieces that I am going to record, so I'm wondering about how to use splitters and adapters without degrading the sound. My assumption is that I will need a 1/4" splitter, plugged into my piano, and the two out ports will go to my headphones, and the other to the comp. I'll also need a 1/4" => 1/8" adapter so I can plug the 1/4" cord into my computer. So I'm wondering if anyone could give me some info on the different brands/types of the above mentioned splitters. There are so many that I can't make an educated purchase... Any help appreciated. Thanks

I was trying for a long time to see if the P60 had a phono output, and I can't see if it does. I Imagine there's some sort of output at the back of the keyboard, either a 1/4" jack or two phono outputs... use this over the headphone output, but if you have to use the headphone output just take a cable straight from the piano to the keyboard, and then plug your headphones into the computer. This way: no splitters or connectors.

As for brands, unless you go for really really crummy cable (the cheapest you can find anywhere that's only 1mm thick) you won't hear the difference... just use as few connectors as possible...
