The height of the glass is set when you put it in. There are 4 screws that hold it in place. You are meant to hold the front side 1mm below the roofline then tighten the screws. Then hold the rear of the glass 1mm above the roof then tighten the rear screws.
I have found that I can't tighten the screws too much otherwise the slider doesn't work properly and the roof catches.
The insulation was just from a local place I found on MarketPlace.

I went with the smaller pre-cut pieces rather than a roll. Made it much easier to put in and mold to the shape of the roof. Then just used metal high speed tape to finish it off. It has come up well and made a huge difference to the heat and noise coming through. Front speakers also sound much better now too. It has worked so well that I will do the rear doors and back of the car too soon.
Pulling the sunroof was much easier than I was expecting. A pain to get the liner out of the car as it is so wide, but it worked. I would recommend leaving the B pillar trim in (where the front seat belts go). Made it much easier to put the liner back in as I just clipped it up over the trim, and the trim held it up perfectly.
