"get it from http://www.virtualbox.org/wiki/Downloads"
no problem installing/running Win XP on a Snow Leopard MacBook. No need to use Bootcamp. Same goes for installing WinXP and x32 bit Linux Kubuntu on my HP with a X64 bit Win7 OS as a host. Virtual box allows you to install more than one guest OS .
none with the product but cnet should have provided a link to Sun Systems so you can choose a correct file to download.
Great softwareAbove mentioned website also has a User's Manual in PD Format
