I bought the same bike last July. I would totally back up the handlebar switch. Mine already had them switched, but I've read in numerous places how horrible the stock ones are. They look pretty uncomfortable too.
As far as going cafe with it, To each their own. I'd encourage keeping all of the stock parts though. The cafe thing is cute and all, but it's a fad that has been dying for a while now. I see people trying to make their bikes into ramblers now. Next fad, who knows, maybe everyone will want to make their bikes look like 80s era japanese choppers. A pretty safe alternative is to get the bike running and just ride it. It will be worth way more as a stock bike, and unless it's in pretty bad shape, then there is no real reason to go trying to change it up. But again, to each their own, no one is going to be able to give you your own opinion on the matter.
