Given how cheap RAM is, it would probably not be a bad upgrade. Your page in to page out ratio is fairly high, so the machine has definitely been memory constrained and swapping. The other benefit is that you'll have more RAM available to be used by OS X for disk caching, which improves system performance as well.
A machine that isn't memory constrained, and that is performing optimally, will have a page in/out ratio of around 10:1 in my experience. One that is badly RAM constrained, like my Mac Mini at home with 2GB of RAM, has a ratio of close to 1:1. You are closer to 1:1 than 10:1.
I say go for it.
