Howdy - sorry for the slow reply! First off, I apologize for the detail but I have no idea if you know all this already or not. I'm no expert and learned all this as part of building our own house and thousands of hours of research. I figure it's better to overshare than provide too little.
Our walls were not parged. Based on what you have said, I'd think the tapcon-equivalent screws and glue would be the way to go though almost certainly overkill. If it's worth doing, it's worth overdoing. In this case, you put glue on the board and spread it with a spreader. You then put the board on the wall and it will lock in place a bit with the glue. Then you drill into the wall through the foam for the screws/anchors. Finally, you just drive the anchors into and it's all locked together - solid and secure and very well insulated. After that, you tape the seams and you now have a tightly insulated basement and a great vapor barrier all in one.
This is the glue we used for the boards we did glue down:

It worked very well and wasn't too nasty to work with. We used a spreader to avoid wasting glue. It also ensures you get good adhesion:

Drilling that many holes in concrete is a pain so you need a rotary hammer (at least I'd highly recommend it - useful tool all around as well). I used the 1 1/8th inch one from Harbor Freight but wished I'd picked up the larger one as it can get bits all the way up to 1 /12 diameter or more. Those huge bits are used to put holes in concrete for things like piping. Either way, it's a lot higher quality than I expected and makes short work of each hole:

We used Simpson anchors as they were a LOT cheaper than tapcons. We got em from a large construction supply house locally:

These need to be driven in along with some large washers. It takes some force so I'd suggest an impact driver using a socket or you'll kill your arms by the third board :)
As an alternative, Hilti and a few other companies make insulation anchors as well - here is a picture of them on Ebay:

These require you to drill the wall and then hammer the fastener in. I didn't use those as I was in a hurry and couldn't get a quick local source of them without costing even more than the concrete anchors I used.
We used pressure treated 2x4 lumber for the fire block - every ten feet horizontally and eight feet vertically. For that reason, it's useful to get the "score board" type XPS foam. It has scoring that makes it trivial to split it in 1/2. That means two full sheets and one half sheet then a 2x4 screwed to the wall. The concrete screws and glue work great for the 2x4 as well.
Finally, you use good tape to seal all the seams to create a proper vapor barrier. This is what we used and it does adhere well to foam:

Whew, lots of stuff. Again I apologize if you already knew this. Please let me know if you have any questions and I'll try to respond more quickly. Thanks and good luck!
