When is “independence of l” known?
For the individual cohomology groups $H^i$, then no.

But what you can deduce is $\ell$independence for the alternating sums of traces.

Ah, actually reflecting on it a bit more, I think I got a bit carried away. What I was thinking was that if the weightmonodromy conjecture were true, then to know $\ell$independence, you need to know $\ell$independence of traces for everything appearing in the $E_2$ page of the weight spectral sequence (since these are then the graded pieces of the monodromy filtration). Now although you know independence of everything on the $E_1$ page, this doesn't imply $\ell$independence for everything on the $E_2$ page (this was the mistake I made).

The topology on the Robba ring
Yes, I wondered about that but I don't think so. There will be elements of $\mathcal{R}_K$ for which that norm is not defined for any $r$, since we require convergence on some semiopen annulus $p^{r}\leq t <1$ rather than the closed annulus $p^{r}\leq t\leq 1$.
