I'm attempting to prove that
all hands that have a five have at least two points. That's why suit doesn't matter. Suppose that I had a hand with a 5 whose only points were a flush. Now, change the suit of one of the cards. Blamo! No more points. I maintain that such a hand does not exist. I have written the program that I intended to write (I'll try to post it once I've cleaned it up a bit), and when considering the cards without considering their suit, the minimum score was two points. You're right about your bullet points though...and we've tried to use them in a more elegant "classical" proof. :)
