GHz: I do not have a meter to measure but from my monkey observations :D, I have experienced the same as wired performance and no lags or cut-outs, just keep the dongle close and not behind pc and on the floor and you will be fine.

If the keyboard works fine the internal keyboard is bad.

The battery life is fine. It's not awful but it isn't great. I get through about 10 hours of gaming and 15 hours of office work on the battery alone with the lights on. Connectivity seems to be good.
