Installed Ubuntu On old Macbook -- Questions

Hey Everyone,

I'm not new to the Ubuntu game, been using it since 9.10 version. However, I recently got a Macbook Pro (older one) and been happy with OSX for the past few months, but got the itch and recently installed 13.04 on a partition so I can dual-boot on my macbook pro.

Questions:
1. Is there any kind of guide out there on how to remap the keys (specifically command key) to work better within OSX?
2. Any way to get the touchpad to work fully? (I got the 2 finger scrolling to work by the mouse settings, but what about the other gestures?)
3. Any other guides out there on how to use Ubuntu with a Macbook Pro secrets?

Any comments / feedback / advice would be greatly appreciated.


Thanks,
