Sharing this information in case it's helpful:

Time: 2.5 hours (maybe 1 hour with experience)
Cost: ~$230-$290 (compared with $470+tax for professional mobile possibly-same-day repair**)

** I saw a post where a Tesla service center did it for $330 total, that seems like the best option.

Parts/tools
1. Glass scraper tool - "Titan Tools 17002 2-Piece Multi-Purpose Razor Scraper Set"** - $10
2. Gloves/eye protection $5
3. 3M 08682 Single Step Primer $20
4. Daubers or brush for applying primer $5
5. 3M 08609 Window-Weld Urethane $20
6. Caulk gun - $10
7. Quarter glass assembly (includes already-installed chrome trim) - $190 + tax
8. Vacuum with a soft brush attachment

** This worked but if I were to do it again, I would look for a thinner scraper, maybe like https://www.amazon.com/Hyde-Tools-13065-Scraper-Folding/dp/B001VEC6BK/

Steps:
1. Order part from Tesla, waited about 2 weeks. Vacuumed broken glass and temporarily taped up window.

2. Removed broken window. This was the hardest part, took 1.5 hours. Prepped by taping off and covering area, although glass pieces were flying everywhere in this step so it didn't help much. First used pliers/fingers to break all glass in the window opening. Then used scraping tool (the long curved one) to cut existing glue between broken glass and metal. This took a lot of effort. Wiggling the blade back/forth seemed to be the most effective cutting technique. There are 3 plugs/clips that needed to be pulled out with pliers. Seemed impossible to do without cutting/scratching the paint, but it seems ok to just cover these with primer later. The process looks like this: Primer Auto Glass photos

3. Followed window install instructions in this video:
.
First used razor to cut level/smooth the existing urethane. Then applied primer on both the opening and the window. After 5 minutes of drying, then applied urethane to the opening. Then set the window by firmly pressing the 3 clips in. Unlike in the video, the position of the window is defined by the 3 clips. This part was fairly easy, although having a urethane gap could result in a leak, and using too much urethane could cause it to overflow out once the window is pressed in.

4. Cleanup. The glass breaks into two sizes, quarter-inch and these tiny dust-like particles. A vacuum crevice tool picks up the large chunks easily, but the soft brush is needed to get the dust-like particles out of the seat.

Overall, might be worth doing if you don't have a low cost service center repair option, if you have some of the tools/experience already, if this isn't the last window you anticipate replacing, or just prefer DIY.
