Dec 11, 2021 at 22:51 comment added Connor Malin @GregoryArone For real Bott periodicity he has a follow up paper clarifying and simplifying certain sections: www3.nd.edu/~mbehren1/papers/addendum.pdf
Dec 11, 2021 at 17:51 comment added Greg Friedman If I recall correctly, I think there's also a nice computation of this in Milnor's book on Morse Theory.
Dec 11, 2021 at 10:03 comment added Gregory Arone Behrens's paper "A new proof of the Bott periodicity theorem" is another source for Q1. www3.nd.edu/~mbehren1/papers/bott.pdf .
Dec 11, 2021 at 0:33 comment added Neil Strickland Q1: Atiyah's paper "Clifford modules" (maths.ed.ac.uk/~v1ranick/papers/abs.pdf) is a good reference. I also explained the calculation in Section 7.2 of my thesis (neil-strickland.staff.shef.ac.uk/research/thesis.pdf). There is nothing significantly original there, but you might or might not find the exposition useful.

Dec 11, 2021 at 0:18 comment added David Roberts To explain that previous comment a little more, which is for Question 1, it's to do with the homotopy groups of $\mathbb{Z}\times BO(\infty) = \mathbb{Z}\times \mathrm{colim}_nB O(n)$, which, IIRC, is a classifying space for $KO$.
