Bottom remapping?

[Funkpod]

Ok, so I've read about how you don't get the ICS quick change button on the new SIii.

Questions
1 is there a way to remap the Menu button so that is does the quick change feature?
2 is there a way to then, the double tap home button feature to get GOOGLE Voice Search/Actions?
3 is there a way that I can add on screen ICS buttons like on the Galaxy Nexus? And then make the hardware home button do something else?

Do I need apps? Rooting?

Thanks!
