You can always install 4GB RAM with XP 32 bit. It will see only 3.2-3.5GB but that's still better than 2 GB.
XP Pro 64 bit had problems that won't be fixed so you would be better off with 32 bit. Just keep in mind that support for XP ends in around a year, which means there will be no new security updates. Any security holes discovered after that will remain unpatched which will leave your computer vulnerable to attack. I can see running an XP machine to the last minute to maiximize use from it (I was using XP until last summer) but it would make no sense to spend money on one now.
