Like you've said, I first plugged the output cable from the mixer to the microphone input of the Laptop. Then I would start up Audacity tp track them one-by-one. I plugged all my mics and acoustic guitar straight into the mixer. I took the line out from the electric guitar amp and plug it into the mixer. It's the same thing for bass.
As for the drums, I used 3 mics to to mic it. One mic would mic the bass drum by placing it directly in front of it, and two would be used to mic the rest of the drums by playing them on each side. One in between the snare and the first tom while the second one in between the 2nd tom and the floor tom.
From there it just takes a lot of tweaking, and adjusting of volume to get things right. Don't worry about getting an overhead mic or whatever because as you can hear, the vocal mics(cheapy ones, mind you) can pick up the cymbals sounds pretty okay, so, I decided not to depress myself anymore with more mics and settings
EDIT: Yeah, great idea from bassbrad. I would be trying out something like this soon
