Upgraded the MacbookPro to 4GB of RAM. Now I can run Parallels and whatever else without any hint of running out of memory. With the cost of ram being ridiculously low, I couldn't see any reason to suffer with Parallels and less RAM. Vista Business is crashing something fierce, but XP seems solid for now. Now I have to work on getting everything off ye olde PC to turn it into a shiny new linux box.
