32Bit OS will only "see" up to 3.25GB of RAM but it is not "wasted".
3GB is sufficient but with the cheap prices of DDR2 RAM. I always suggest getting a 2X2GB matched pair.
You can install XP "over" Vista. XP will ask you if you want to Delete the present OS on the Hdd. You select Yes. Personally, I prefer to wipe the Hdd with a third party app. DBAN-UBD-Killdisk
Be CERTAIN you have the Mobo drivers for XP. If you have a custom built PC, the drivers will be on the Mobo CD.
If you have a pre-Built PC, check the manufacturer's site for the appropriate drivers. (i.e. Chipset-Video-Audio-Ethernet)
