Q1 - Since you play 2/1, if the opponent had passed instead of bidding ♠, what would you have bid with hand 1? If you're not playing any special major raises, you probably would have bid a forcing NT and then jumped to 3 ♥ over partner's rebid - the invitational 2 1/2 ♥ raise. 4-3-3-3 isn't ideal, but as JLOGIC pointed out, your ♠ K gained some value positioned behind the ♠ overcaller. You'd like to have 4 ♠s for a limit raise, but you do have the right values to make one. So, 2 ♠ showing invitational values would seem right to me.
Q2 - I'd start out with 2 ♠ on this hand for a couple reasons. First, if the points are evenly distributed around the table, 2 ♠ makes it more difficult for the opponents to find their red suit fit -- they've got to do it at the 3 level. (And for this reason, I don't have any problem with those who might want to preempt it a bit more aggressively.) Second, partner is unlikely to make a competitive decision that expects more from my hand than I have (i.e. 1 1/2 QTs).
Q3 - Given the auction to this point, you have a clear pass. You've already aggressively bid your values and have no idea what partner's RDBL was based on. So give partner a chance to decide what to do and make a further call. Partner might support ♠s, or double to try to find a better place to play (after which you can bid ♣s), or might just sit for 3 ♥ with the right hand to defeat it.
