Regarding the dist folder and the APK in it, this is the unsigned new built app, it contains exactly the same as the <apk>/built/apk folder. It means (although I have never tried it yet) that copying the META-INF folder and AndroidManifest.xml (not 100% sure about this one) from the original APK into it should do the same trick as moving the resources.arsc and whatever was changed within the RES folder from the built app into the original one. Hope I explained myself clearly... LOL
The signature is actually in the META-INF folder on the original APK, that's actually the reason you need to move the files back to the original APK. I don't believe you can actually sign a system app as it needs a special system signature, I'm not so sure about this one but I've tried before signing one and it just FCed.
