For the doors go with tempered Glass 1/4in because that is the standard track size
Get the glass and sliders from a local glass shop I got all my stuff from Goldfinch Bros Glass here in Seattle but I am sure there is a local company close to you.
You may have to make a call or 2 I did but once I found a good supplier they have been greatmy doors are 10.25 X 22.5 in and Glass, Tracks, Stick on Handles cost me about $40 so good luck and I am sure there is a Glass shop near you
