comment Minimal Discriminants
Odlyzko mentions this problem in his survey paper dtc.umn.edu/~odlyzko/doc/arch/discriminant.survey.pdf asking whether the root discriminant goes to infinity for prime degrees (see open problem 2.4). I don't think much more is known about it, although I would love to be wrong here!

comment $L^1$ norm of exponential sum of $n^2 x$
@tdw: Dear Trevor, From the works ofJurkat and van Horne and Marklof, the quadratic Weyl sums have a distribution that is not Gaussian. So the constant in the moments, I don't think needs to match your conjecture. The constant they get is by averaging moments of a theta function over a fundamental domain. It is possible that for the first moment this could evaluate to your conjectured value, but I don't see why. In any case, the distribution is not Gaussian, which seems quite different from other powers. Am I missing something?

comment Approximate homomorphisms
I was thinking of the ideas around Corollary 2.4 in that paper. (And also that ${\Bbb Z}/p$ for large enough $p$ might behave not too differently from ${\Bbb Z}$.) Anyway, just a quick thought.

The techniques in this paper arxiv.org/pdf/1308.2247v1.pdf might be useful.

comment The sum of squared logarithms conjecture
@JohannesHahn: I'm surprised by your comment. The question clearly states a conjecture and asks for a proof -- what's not on topic about this? And, anyone who doesn't want the gold can pass it on to me!
