Use [ and ] to type 「 and 」. {} will give you『』.

とか is pretty easy. It's similar to や; it's essentially an "et cetera" particle. You could translate it as "things like ~".

Are we talking about a sentence-final なぁ there? It's a masculine-ish mild emphatic, similar to ね. (As opposed to な, which when placed after a verb in plain form is a rude negative imperative -- するな would mean "don't do it!" as the negation of しろ "do it!")
