Hey, windham, it's great to hear that you're trying it.
As for brushing your teeth: like I said, you need to reapply the aquaphor before you brush your teeth. And when you're brushing your teeth, just make sure not to stretch your mouth too much. It's okay if water hits your lips--I certainly let it. And I had a bit of difficulty flossing, but I managed to do it anyway. When you're finished brushing, gently glide over your lips with a toothbrush--whatever isn't part of your lips should come off. Don't force anything. I repeat: don't force anything. Then reapply the aquaphor.
Honestly, though, I wouldn't worry too much. Whatever damage you might do will eventually heal itself if you diligently apply the aquaphor afterwards. You should be fine within 7-10 days.
I'm going to make another post soon to update everyone and to add some details about certain aspects I didn't touch on before.
Just know this: my lips do not exfoliate SHIT anymore and I am perfectly healed. My lips are as normal as they can possibly be. I do have scarring on the inside, though, where the root of the scabs were--but I love that shit, truth be told.
EDIT: I just read your post in your original thread. Yeah, like I've said in MY original post, if you leave the scabs alone you'll eventually heal, like daniki and others. Even Daniel's lips partially healed while he left them alone. The problem is the location of the wound: we stretch our lips constantly when we eat or laugh or smile or talk or yawn or whatever. All this movement prevents the scabs to form properly, so that they never fully cover the wound, which is what a proper scab is supposed to do. That means that the healing slows down to a snail's pace--making this simple process take months or years. 8 weeks is nothing; I've seen a guy on Daniel's site who claimed it took him 2 and a half years to heal by leaving it alone. It works, if that's your cup of tea. It certainly wasn't mine.
