This is the most important one, that's not been mentioned in OP:
defaults write -g NSScrollAnimationEnabled -bool NO
It disables the stupid "smooth scrolling". on Lion (and everything before that) you could disable it from the 'General' tab of SysPrefs, but now it's gone.
What does it do? When you press spacebar in a web browser, or fn-downarrow in a text editor, it "smoothly" bring new content up from the bottom of the screen and pushes current screen up.
I don't know, maybe it works great on recent machines, but my poor old 2009 MBP's graphics card is not really powerful, and this animation is not smooth at all. It distracts me a lot.
I strongly suggest you at least try it. If you don't like it, just replace NO with YES and everything's back to normal.
I'm completely the opposite; having windows contents jarrigly jump down slows me down significantly as I keep having to scan to find my place. It's one thing that annoys me about vimium that there's no option to j/k scroll smoothly
