How to compute with the Stark conjectures?

I would like a convenient basis for the elements of a fixed abelian extension $E$ of a real quadratic field $\mathbb{Q}(\sqrt{d})$. The accepted answer to this MO question suggests that the Stark ...

Existence of imaginary quadratic fields of class numbers coprime to $p$ with prescribed splitting behaviour of $p$

Let $x\in\{\text{totally ramified, inert, totally split}\}.$ If $p\geq 5$ is a prime, are there infinitely many imaginary quadratic fields $K=\mathbb{Q}(\sqrt{-d})$ of class number coprime to $p$ so ...
