(Okay, “basement studs” sounds like a bad 80s porno, but you get the idea…)
Fixin’ to insulate and stud out my basement this fall/winter. We’ve got 9′ poured concrete walls, I-joist construction above.
I’m planning on using the method recommended by Building Science Corp – XPS or EPS against the wall, studs against that. Barring any need to do otherwise, I imagine I’ll run the studs in flat to keep my rooms as large as possible.
What isn’t clear to me is whether or not the studs should be fastened to anything other than the top & sill plates, which will obviously be nailed/screwed as necessary. So, my questions:
1) Do I need to Tapcon the studs through the foam and into the concrete?
2) What’s the generally accepted method of affixing the foamboard to the walls? Glue?
Thanks.

No the studs don't need to be attached to the foam/walls. They are going to backed up against the foam anyway.
I did one, but only 7ft tall suing 1 5/8" metal studs and it was plenty stiff.
How I had an unusal situation. The walls where cracked and bowed. But it had been structurally fixed.
But I used PL Preminum to hold hold them the foam in place. The used great stuff to seal to the floor and ceiling and sheet to sheet.
Note, check on the adhesive package. Some will attack stryofoam.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.

Did you mean attack?
the Styrafoamiisa aren't terrorists. Why would he attack them?

Do you guys put electric in your basement walls?
What do you do with boxes and wire?
I don't do studs. I use glue for th efoam, then strapping over that with tapcons into crete

You should also consider doing closed-cell foam insulation instead of the foam panels. Higher R-value and better thermal seal. Did that in my basement and very happy with the results. And if you're planning to have outlets in the outside walls, installing on the flat is probably not the best idea, and you're just talking a few lost inches with more ridgid and straighter walls.

1 5/8" 20 gauge steel studs will save space and give you a rigid wall. Space them 1/2" from the foam and you can run wires behind them.
