No, I moved the lot over, the fiddly (read pain in the butt!) part was making sure the page file partition was at the beginning of the second disc. Just took a bit of juggling with files / partitions to get it there.
Me? If I had 8Gb of RAM and working on the 1.5 factor (but as you say let Windows physically control its size) I'd set my partition at 16, maybe 20Gb for a round number, depending on space, which, on paper, will not be a problem for you!
**For page file read Swap file!! Its been a long day
