I don't manually kill apps unless they are hung, or I can see that they are using way too many resources and I can't stop it by just pressing 'back'. Other than these rare cases, I never kill apps, and neither should you. For a detailed analysis why, take a look here, written by one of the google developers that created Android:

There are no special considerations for charging Lithium-ion or Lithium-polymer batteries. Charge it any way you like.
I believe in ICS, you can disable apps via Settings > Apps. Go into the app in question, and there should be a Disable button.
I am rooted, and over at xda, there was a post that suggested some tweaks to the build.prop file that would make things smoother, faster, better, etc. But you need to be rooted to make the changes.
