Also, the guitar and vocal share common frequency which means you have to be carefull when mixing them. One very important thing is to pan your tracks so everything is not straight in the middle. You have a panning option on each track. You can pan from full left to full right, this is your stereo field.
Try this, record your guitar track, then your vocal track. Pan one track 50% left and vocal 50% right. You'll hear the difference, everything will be a lot more clear. It's going to be easier to adjust levels. Now mixing techniques is a whole other beast to learn and altho I've been recording for many years now, I'm still learning everyday.
One of the thing that often happened to me in the beginning is that I had some other softtware (winamp for exemple) that would mess with my windows audio settings. So when I would go back to my audio recording session, everything was either way louder or softer than before. Long story short, I now have one computer just for recording :)
A simple easy mixing template is to pan the following
Bass = straight middle
Rhythm guitar 1 = panned 80-90 left
Rhythm guitar 2 = panned 80-90 right
Vocal - straight middle
drums = very complicated, depends on your gear. I use loops so it's already panned correctly.
Like I said, I'm so expert on mixing but I've enjoyed home recording for years. Once you get the levels correctly, take not of every knobs of level you have and write it down :)
