I need help with windows

What type of windows are acceptable? What type can be used? how are they installed???
I'm still debating insulated walls or uninsulated, so what works best.
I was thinking about using two storm windows on the door, a regular one on the outside, and a custom on the inside (Window locks on the outside, no screen). Are house windows acceptable? (I got my hands on a free anderson vynle window)
How about a sky light? I could use two picture storm windows(no screen, single pane of glass) again, one inside, one out. Would this turn the TD into one of those boy scout solar ovens?
