So I'm thinking that the boy in the woods is no more than a dead body fo Jacob to manifest as, just as MIB manifested as Alex, Yemi, Libby etc.. I think that as Smokey is now stuck in John Lockes body, Jacob also needs a body, the so called "candidate"..
In regards to Jacob touching them in their past I think it may have something to do with what they can see.. for example Sawyer could see the boy in the woods whereas Richard could not.. Jack could see his father and Hurley can see a number of dead folk!
I'm gonna hazard a guess that it was Jin "Kwon" on the wall because Sun wasn't supposed to come back to the Island..
Loved this episode.
