How to find an element of high-order in an RSA group?
Is this even possible? The RSA group is not cyclic, so usually you wouldn't find a generator for accessing all group elements.
What happens if you use the RSA group in a scenario where you want that ...

Why work in a subgroup QR(n) of an RSA group $Z^*_n$?
I sometimes read in papers that a (sub-)group generator $g$ is taken from $\mathrm{QR}(n)$ instead of $\mathbb{Z}^*_n$, where $n = p \cdot q$ and $p$ and $q$ are prime. Is there a reason for this? ...

Would the ability to efficiently find Discrete Logs have any impact on the security of RSA?
This answer makes the claim that the Discrete Log problem and RSA are independent from a security perspective.
RSA labs makes a similar statement:
The discrete logarithm problem bears the same ...
