It sounds like you'll have to use
NDISWRAPPER or
DRIVERLOADER to get it up and running.
They both do the same thing. One is free (ndiswrapper), one is not (driverloader). They use the Windows Network API to run your card. This way, you can use the Windows drivers that came with your card. I'm not positive, but it looks as if your card isn't supported under linux (no linux drivers), so you'll have to use one of those two programs above.
I use driverloader on my laptop and it works great. You get a 30-day trial with driverloader, and in my expierence, it is MUCH easier to setup than ndiswrapper. Being that you are a "noob", as you say, you might want to opt for trying the trial of driverloader. If it works and you don't mind forking out $19.95, you could just get the full version (activation license). You won't have to re-install or re-configure anything; just enter your license code that they give you after you buy it.
Post back if you have any problems with driverloader. I'd be more than happy to walk you thru it if you need any assistance.
