Is anything known about the eigenspectrum of the regular representation of the permutation group?
The two answers appear to assume that you want to know the spectrum for the action on an arbitrary irreducible. If you are really only interested in the regular representation, then @ARupinski's comment is all you need.

Can topological cyclic homology compute Picard groups?
If $A$ is the ring of integers in number field, I think it is true more generally that $A_p$ is a finite product of discrete valuation rings and so has trivial class group. I think that your line of argument can therefore be adapted to show that $K_0(A)\to TC_0(A)$ always kills the class group

Extension of conformal map and annulus
I don't think that this is correct. Why should there be a Mobius function?

Are Bökstedt's THH manuscripts available?
You could just email Bökstedt and ask him about putting his old preprints online. He is still active, and his recent papers are on the arxiv, although it may be that his coauthors did the work of uploading them; he does not seem to have a home page that he maintains himself. Maybe you could approach one of those coauthors and ask them to negotiate with Bökstedt.
