You'll need the front and back of the roof unlatched.
I think the hard part will be taking down the entire headlining, the rest is pretty straight forward.
There is a set of clips behind the cloth trim at the release. Pop those clips and the release will slide out. After that, remove the screws across the front of the 1st bow and you can pop the trim off -- use care the clips on the sides are fragile.
With the front trim off, remove all the screws that hold the headlining to the roof and then pop the front wire off the hooks on the 1st bow.
A couple plastic rivets and the headlining support channel on both the 2nd and 3rd bows will pop off. Release the elastic straps at the 4th and 5th bows.
From here, you'll have access to the clips that retain both the headlining to the window surround and the window to the top. I'd start by gently prying each clip up just far enough to remove the headlining's support ring.
Once the headlining is off, pop off the clips and remove the old glass.
Reassembly is pretty much the reverse except the headlining pops back onto the rear window clips after the rest of the headlining is mostly installed.
