Yamaha 01v + G5, Yamaha 01v + G5 Options

How can I get a decent recording from an 01v on a PowerMac G5 2GHz using GarageBand? I'm ashamed to say that I've been recording just by plugging the 01v headphone output into the PowerMac's audio input. This has worked fine just recording my turntables but now I'm trying to also record a vocalist, bass player and guiter player and the sound is horrible. I would like to get a nice setup but for the time being I'd really just like to record the output from the 01v, single track, just very simple if possible. If someone could point me in the right direction I'd appreciate it, thanks.
