RCA is OK, I can only help you with Vinyl.
Download Audiograbber (www.audiograbber.org) and download from the same site, the Lame encoder, follow the instructions and play around untill you get to know the grabber, if you want to record to CD use media monkey, I tunes burns bad disk. You can burn to disk from the Grabber but media monkey is better. If you have alot of Vinyl you are in for a long run, its like when we recorded vinyl to tapes.
You vil have to add titels, Artist, genre and tags by hand;
There is another good player out there, Jaangle, its only a player, if you give in the tags when recording, Jangle will search the internet for pics album covers and artist descriptions, better than any other player. Better playback than Itunes
To save space I convert to MP3 320 Kbs.
If you have problems, mail me and I will walk you through it
