Can $T$ act trivial in a repn of SL$_2(\mathbb{Z}_N)$?
Be careful that $p$ is much easier than $p^k$. I actually don't understand your proof even for the case $p$.

PhillipsSarnak conjecture in higher dimension
What about superrigidity? Does it not contradict your claim about existence of nonarithmetic lattices in higher rank? en.wikipedia.org/wiki/Superrigidity

comment 
Are the only discrete groups with nontrivial padic Haar measure finite?
What is a tight measure? How is the isometry between $M(G)$ and $c_0(G)$? Usually $c_0(G)' = M(G)$, so there is a dual. I can't actually see why it should matter $C_p$ or $C$ valued measures here. It is more likely to see where you go wrong if you add all definitions.

The sum over zeros in the explicit formula for $\zeta(s)$
If you mean the explicit formula of Weil, the test function should be bounded by $(1+\im z))^{2 + \epsilon}$ and we also have absolute convergence there. So I am not sure if your argument can be made rigorous, because it would imply an explicit formula with more relaxed conditions on the allowed test functions.

What is the current status of representations of $GL_n(F)$ (and other algebraic groups)?
I also recommend BushnellHenniart Local Langlands for GL(2) for the BushnellKutzko theory. It is more digestible for a beginner, I think.

When $F$ is local nonarchimedean field,...

What is the intuition behind the definition of cuspidal representations?

Yes the unipotent radiacal of any Borel subgroup (defined over $F$). Note that your are allowed to conjugate by elements of $GL_2(F)$. There are may expositions on how to move between classical and adelic language, see e.g. Bump's book.

leadingorder behaviour of riemann zeta function?
$\zeta$ gets arbitrary small in $1/2 \leq \Re s <1$. I am not sure about $0< \Re s <1/2$.

I am not getting it? Is your "I'm looking for something...." not stronger then LH, which is certainly not known?
