So do I even need a page file for a system that has 8 or 12 GBs of RAM?
7 will pretty much handle this stuff automatically such as disabling automatic defrag on the disk, disabling superfetch, and other system services unnecessary on an ssd.
Just do a fresh install on the drive without going outside of 7's guided install process and do the prior mentioned pagefile and hibernation tweaks and you'll be fine. No need to overthink it.
