I know this is an old thread but.....
"2) I have my WRT54G configured to use WPA2 Personal currently. My laptop with Windows XP Pro and wireless-G card doesn't offer WPA2 as an encryption method from the wireless utility. However if I select WPA it works. How is that possible? Are WPA and WPA2 compatibile? "
Right off the help page embedded in the router: "WPA2 Personal:
WPA2 Algorithm: You may choose from AES or TKIP+AES. Choose TKIP+AES if you have both WPA and WPA2 devices on your network."
I hope that helps someone.

Sometimes encryption nomenclature is confusing.
WPA = WPA with TKIP = PSK
WPA2 = WPA with AES = PSK2
When your router is set to "WPA2 with TKIP+AES" it means that network devices that can use WPA2 will connect with WPA2, and network devices that can only use WPA will connect with WPA. The password for both WPA and WPA2 will be the same. This option was added to allow users to easily transition from WPA to WPA2. To set your router to use only WPA2, choose WPA2 with AES (do not use TKIP).
Also, it is very unlikely that your wireless g card cannot do WPA2. It may be listed as "WPA with AES". If you do not see WPA2 or "WPA with AES" as an option, then download and install the latest driver for your wireless card. The updated driver should support WPA2. Also note that in order to do WPA2, you will need to upgrade Windows XP to SP3.
Note that if all your wireless devices can do WPA2, you should set your router to do WPA2 with AES (not with TKIP). This will improve the security of your network by eliminating the use of WPA encryption.
