Seems we need a WiFi FAQ, I might not be the one to start this but here goes. Firstly:
What's the difference between the different protocalls a/b/g and such?

There are several specifications in the 802.11 family:
802.11 -- applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
802.11a -- an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS.
802.11b (also referred to as 802.11 High Rate or Wi-Fi) -- an extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet.
802.11g -- applies to wireless LANs and provides 20+ Mbps in the 2.4 GHz band.
Where can I mount my antenna?
You should really mount your antenna outside your car, metal will block the high frequency WiFi signal pretty easily. Glass will interfere some but not as much as metal.
Can I use my car's AM/FM antenna to recieve wireless?
No, as antennas must be tuned to the proper length depending on the frequency of the signal. Radio signals are a much lower frequency than WiFi and as such require a much longer antenna. Also, WiFi antennas send as well as recieve so they must be powered, powering an AM/FM antenna with your wireless card can fry things so be careful!
What else?
What's the best antenna?
