First of all, be preparted for some serious study Diving headfirst into backtrack if you're new to linux is a big step. What alfa card do you have? The AWUS036H works nicely with BackTrack out-of-the-box. I'd disable your internal wireless before booting BT. Since you're new to Linux & BackTrack, this will help reduce possible problems. Rather than use iwlist, use one of the tools in the BT distro for wireless stuff...aircrack suite, kismet, etc. They will take full advantage of your card.
