1. In standard and in some variants of 2/1, 1N is not forcing by a passed hand. A significant group play it as semi-forcing, while in my experience only a small number play it as forcing. It is important that you have a firm agreement not only on this but also on whether you open 4 card majors in 3rd and 4th: if you do, then playing 1N as forcing is a poor choice. I happen to believe (as do the vast majority of good players I have played with or against) that 4 card majors in 3rd and 4th are a good idea.
2. I would raise ♠ as a passed hand. If we are playing 4 card majors, then we are (I assume) playing that 1N is at most semi-forcing. Thus there is far too great a risk of playing in 1N, and this is an excellent hand for ♠. If we are 4-4, the short hand is scoring ruffs, which adds greatly to the trick taking potential of the hand. Plus, if partner has 5+♠, he is more likely to be encouraged to probe for game than if you make a support-denying initial response. And if 1N is forcing, then this hand is too good for the slow road to 2♠.
3. I tend to rebid 2♦ with these hands regardless of the degree of force connected with the 1N. I can see passing 1N at mps, but not at imps. It is entirley possible, looking at the south hand, that any of ♦/♥ or ♠ may be better than 1N: so you have 3 ways to win by bidding and only one way to lose (that is a slight oversimplification, of course).
