Don't the Tesla chargers charge faster than normal ones? DO you know the difference in time between the two types? What's going to happen when the government installs 400,000 chargers and the car design changes in years hence? Will chargers come with memory cards or wi-fi so I can dump or upload my photos while I'm charging my car?
In order:
1) Some do, some don't
2) Not offhand. There's a pretty easy calculation of Kilowatt hours to battery size to time to charge, but I don't know it offhand. For my purposes, I plug in at night and the car is generally "full" in the morning. That's a small battery and just a regular wall plug charger.
3) Probably everything will eventually be standardized, more or less like regular domestic power outlets.
4) That would be pretty cool. With Musk's satellite ideas, I could definitely see wi-fi being standard at Tesla Superchargers.
