Probably the best thing to do if you're having trouble is to take it slowly and test each step. Before you get to the part about editing the smali, compile your apk and see if it works in your phone.
If it does, try the smali editing. If it doesn't, share your XML here and I'll see what I can do to help you.
Android modding takes a bit of practice to get used to. But once you do, you'll be able to do stuff like this in your sleep!
It took me about two months from rooting my first Android phone to being able to change the battery icon..and that was on Android 2.1 which was a lot easier!
Just have patience and you'll get there.
