Using other wireless usb

Hi, firstly i want to say hello, because this is my first post.
I will have on 5 days my first macintosh, a macbook.
I am an advanced user of Linux and Windows, and knoe i decided to have a macbook, in which i will have triple booting or dual boot and windows in parallels.

I have to use in my work a fake mac, to monitor the network, and then i cannot do it in Mactel, because mac spoofing is not possible yet, and my question is. If i use a USB wireles device, that doesn't have mactel drivers, is it possible to use NDIS drivers to use it, like ndiswrapper in Linux?
If it is not possible, which USB device you recomend for doing this (monitor), but it needs to have an atheros chipset, which will be used by madwifi-ng

Can you help me?

Thanks a lot, it is the only thing i think i won't be able to do with this fabulous OS.

I heard about "sudo ifconfig lladress xx:xx:xx:xx:xx" more and less. does it work on my macbook 2 GB doble core 2?

Thanks a lot, anyway, i like anyone can help me with the previous post
