On the T60, due to hardware restrictions, you wouldn't be able to use more than 3GB of the installed 4GB RAM, so installing an additional 2GB module replacing one of the existing 1GB modules should be sufficient. And yes, Win7 will make your T60 more responsive to such a degree that you would actually note it.
While i do prefer Linux for everything since more than 15 years, i have to admit that Win7 has become much better than any of it's former Windows incarnations. For my taste it is still far from being good enough to lure me away from Linux, but at least already good enough to not want to have to use any of it's ancestors at work. Seems like Microsoft has at long last started to invest more effort into actual technical advancement than just only in marketing.

You are aware that putting a pillow in between lap and laptop does indeed block the required air flow of the cooling unit? Maybe changing this bad habit might also help. Try something with a hard surface instead, so that there is a gap left under the bottom of your T60.
If your T60 still runs too hot, and since it has already a few years on it's back, it might also be advisable to refresh the thermal grease between the CPU/GPU and the fan unit.
