Check out this link for some pretty nice software and some plug ins for LP transfers. I have tried the trial version and sonically it is very, very good.

You will still need a phono preamp to raise the levels and a decent sound card to input the analogue to digital for wav files or conversion to MP3's, what ever floats your boat. If your audio set up has preamp outputs you can use that as well to stream into your computer.
