A convergence issue
From your definition of $l^2_{k^{2}}$ it looks as though every element of $l^2$ belongs to this space. And therefore $l^2_{k^{2}} = l^2$. Is that really what you meant?

I think the best answer is to refer you to the Mathematics Subject Classification. If people try answering this question it seems like it would turn into a popularity contest. Anyway, voting to close as I don't think it's an appropriate question.

References for von Neumann Algebras
Not an expert, but I'd say Takesaki vol. 2 is a good place to start.

A question on limit of weak* convergence of probability measures
Still not research level. This belongs on math.stackexchange.

The answer is no, but I don't think this is a research level question.

A “coarse” version of position operator and its properties
@physicalmaths: it's the Fourier transform, suitably normalized to make it unitary. I think the formula for $P$ is a typo, it should just be $P = U^* Q U = s(p)$.

There's no general definition of the commutator of two unbounded operators, and in this case I really don't see any sensible way to interpret your $[Q,P]$.
