There was a lot of other surprises in there as well.
The woman in the accident was Jacks future wife.
The man brought in at the same time, ie the one she hit was Shannon & Boones father.
The scottish guy is the same one Jack saw at the stadium.
If you notice the Quarantine sign was on the inside of the door meaning the island is the quarantine, not the hatch.
When walt appeared to shannon, he says 'Dont push the button, the button is bad' (hint, you have to play it in reverse), presumably meaning the execute button on what looks like a C64.
By the looks of most of the stuff I'd say about 1970s but the washer & dryer threw me because they looked pretty modern. I also noticed he had an american pistol but russian rifles (ak47). I also suspect that Locke has already met him or been in the hatch before, if you think about the episode when boone dies, he goes to the hatch and hammers on it 'I did everything you asked of me'. I think he has met desmond before and that he needed the heroin from the plane but knew it was unsafe. Not sure about that bit though.
I believe that next week deals with the raft from the previews at the end of epi 1.
