Just checked the first 3: 気がつくis just a set expression that's in the dictionary, not a grammar point which explains a way to build a sentence. If you want a grammar point for "I notice", you need one for "I think", "I say"... There are grammar points with 思う言う, but not for the direct meaning.
irassharu is one of the words that one learns when he discovers sonkeigo (minna 49, for example), it's not a grammar point in itself, is it?
dakede: meh... maybe?
I'm not significantly more advanced than you, probably, but you asked for any thoughts, here's mine.
