comment Is the functional equation for $\zeta (s) \left(1-\frac{1}{3^{s-1}}\right)$ known?
Yes, just change $2^{-s}$ to $3^{-s}$ (and $2^{-s-1}$ to $3^{-s-1}$) in the func. equations for $\eta$.

comment The form of the zeta function of an elliptic curve over a finite field
And of course a proof for $y^2=x^3-x$ goes back to Gauss (see e.g. Ireland, Rosen. A Classical Introduction to Modern Number Theory, ch. 8 for the proof)

Well, there is a relatively elementary proof in Silverman. The Arithmetic of Elliptic Curves
