The seatpost is 27.2mm, that's a pretty common modern standard for aluminum frames.

You can convert the mtn bike hub to single speed, there are 2 different kinds, freewheel and cassette. Which have you got? The process is different depending what you've got, and it does require a special tool to remove the clusters usually, unless you want to get creative.

Inside locknuts (preferred):

Outside locknuts:
