The End is near, but I'm hoping to get a couple more miles out of this computer...

My Macbook Pro is definitely on it's last legs. The battery is on critical, RAM is depleted, and the **** track pad doesn't *click* anymore. I'm looking for a way to drop as much non-essential, for lack of a better word, stuff from my computer so that at least it will work a tad bit longer (and hopefully better) before I inevitably have to replace it.

Any advice?

Here is my read-out from EtreCheck:
