1. Any comment about bidding?

♥, now how many spades do you cash before you try cross-ruff? Or do you have a better way to play that does not need cross-ruff?
By the way, opp didn't give you count when you cash spade, of course!
Given that they did not compete to 3C, north is marked with 6 clubs. If you cross to the K of spades and ruff a club, then that will establish the club position. Then you could ask "would AKJTxx + an outside singleton qualify as a preempt at this position". That would be useful information.
Other useful information would be the level of the N player. The lack of a trump switch is interesting. Given that he should know that you are 5-4 in the minors, you he might think that he would be concerned about the cross ruff. Moreover while he knows you have one card, he will not know whether it is the K of spades or the Ace of diamonds.
If the spades are 2-4 (they are unlikely to be 4-2), then the defence can get a spade ruff anyway by overruffing the second club ruff and returning a spade, and then producing another trump. That defence would work if LHO is say 2-3-2-6. or 2-2-3-6. That will restrict declarer to 9 tricks. However, its hard to beleive that rho has Hx club and 4 spades and Ax diamonds and did not find a t/o dble.
Perhaps then the best line is to cross tot he K of spades, ruff a club with the K, ruff a heart small and ruff a club with the Q. RHO is now in a tricky spot, if he pitches a spade you can now cash a second spade and score 2 spades, 3 club ruffs 4 diamonds +1h for ten tricks. If he overruffs and returns a trump you can overtake in your hand, draw all the remaing diamonds and you will make 4 spades 1h 5d + 1 ruffs = 11 tricks if the spades are 3-3, or 10 otherwise.
EDIT: Just saw the board, yes I will make ten on this layout with the line given. 11 if south overruffs a club with the ace of diamonds to return a trump, which is an understandable defensive error.
