I wouldn't really relate our healing process to wounds and scabs. I've been leaving my lips alone for months now and layers have built up so now I actually get real cuts in my lips again and they heal in about a week. The process of building up layers is different to a cut.
As for the wet thing I wouldn't worry too much about it, when I first started doing this my lips were so so dry they really hurt but it gets better I promise. The key is to try and not disturb the fresh skin and crusts. I shower daily I just turn my face away from the shower and lean my head back to wash my hair. Don't worry about it to much just let them air dry afterwards.
