you didn't mention if you were using the usb interface (
UCA-202 i think) that came with your mixer. but ill assume that you are.
first step will be connecting your mixer to your interface. youll use some RCA cables to go from the TAPE outs of your mixer to the Input on the interface. then youll connect another set of RCA's going from your interface output to the TAPE in on your mixer.
then connect your interface to your computer through a usb port, and your computer will automatically install the drivers (given that you have xp or higher)
then on your sequincer, or recording software, youll want to go to prefrences and change the ins and outs to "USB AUDIO CODEC." you might have to change ins and outs inside the microsoft mixer(the little speaker on your task bar)
then connect a mic or something to your mixer and turn the levels up on the channel level, master level, and the preamp level if necissary.
this should be bassically all that there is to it let me know if it helps, i might have forgotten a step or two though.
good luck

oh btw if you want to moniter whats being played back youll want to change the 'CTRL Room' level fader on your mixer.
