Start Screen is dead not Start Menu. The old Start Screen (like in 8.1) has morphed into something new that "to me" looks like some of both.
I don't know, I did an Enterprise install on my laptop and got the new Start Menu. I did a clean install though. Same deal on my desktop PC with the non enterprise ISO.
Charms have been moved into the Notification tray. I don't think they're called Charms any more though.
You should see tiles at the bottom of Notifications that do much of what Charms did.
Hit the up arrow ^ in Notifications to show more tiles
