No advice from me but good luck to you. Strained glass is beautiful and I once thought I wanted to experiment with it. Then I found out it was going to take a lot of work and tools, so I decided I wasn't ready to tackle anything that complex. Scrap-booking is more my speed.
I'm not sure where you could get supplies online but my local Hobby Lobby store used to carry soldering irons and sheets of glass about one foot square for small projects.
