Answer 1

Probbably all you need to know about that is in this very good article from Cyril Mottier : http://cyrilmottier.com/2014/08/26/putting-your-apks-on-diet/

Read the part about Lint ("Use Lint extensively"), as it's the tool that allow you to remove unused resources.

Hope it helps...

Answer 2

I almost missed it to write that there is now a nice solution:

android {
    buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
        }
    }
}

This was annouced on Google+ by Tor Norbye for the build tools version 0.14.0
