I'm a complete newbie, and am trying to understand how the strong auctions work. For now, let's focus on north / south, and ignore the competitive aspects for now, so I can better understand the strong auctions.
North will open 2♣, the strong 2♣.
South will probably respond 2♦, since even though he has more than 7 points and 6 spades, the spades aren't that strong.
The 2
♠ response normally shows five spades to two top honors. However, the sixth spade is really valuable and I would rather have king-sixth than king-queen-fifth most of the time. I think bidding 2
♠ here is a good choice for south. But not everyone will agree; 2
♦ is okay too.

North will then bid 3♣, since clubs are his longest suit.
South doesn't have a fit for clubs, but has a reasonable hand and a decent spade suit, so he'll probably bid 2♠ next.
After north's 3
♣ bid, south must bid at the three-level. He will bid 3
♠ next.

After that, I don't know. How does sounds know how strong north is? Obviously, the belong in at least game. But would 4♠ be seen as a signoff? I see nothing about south's hand that would suggest slam. But let's say that south wants to gamble, and bids 4NT, Blackwood.
After hearing 3
♠ from south, north knows slam is pretty likely. If south has king-fifth of spades then we will make seven. So north cannot bid 4
♠. He must bid something more. A simple choice would be 6
♠, which can make even opposite five small spades with a little luck. Another option is to bid 5NT ("grand slam force") which is asking south to bid 7
♠ with good trumps. Good trumps in this context should be "a top trump honor" since two top trump honors seem too much to hope for given the bidding.

How does north respond to show 3 aces and a void? I know to show 1 ace and a void you bid your void suit at the 6 level if the void is lower ranking than the trump suit, or bid the trump suit at the 6 level to show a void higher ranking than the trump suit. I know that to show 2 aces and a void you bid 5NT. But I have no idea how to show 3 aces and a void. Do you just ignore the void? Or is there a way to show it?
The usual agreement I've seen is that you bid your suit at the 6-level to show an
odd number of aces with a void. Usually partner can tell between one and three from his hand and the auction. Here a jump to 6
♥ over blackwood is "one or three aces with a void in heart" but remember north opened a strong 2
♣... it will be three aces and not one considering.

Realistically, I doubt that south would bid blackwood anyway. South has no first round control to cuebid. Should south just raise to 4♠? Would that be a signoff? Or should south cuebid 4♦ to show the K♦? What would north do next?
Let's say south bids 4♠ and it's not a forceoff. North has a first round control in every suit, but cannot bid Blackwood since he has a void. North is mostly interested in finding out if south has the K♦ and K♠. A cuebidding sequence can locate the K♦, but I'm not 100% sure how. But what about the K♠? North can't bid the grand slam force either, since he has 2 of the top 3 honors in spades. Even if you play RKCB, north can't bid that either, with a void in hearts.
If south has to somehow find a bid over 4
♠, then the 5
♦ cue is ideal. Of course, north "signing off" in 4
♠ seems unlikely in any reasonable auction.
Grand slam force must be interpreted in context. It's just "bid a grand if you have good trumps." Here, south could have a pretty weak hand and didn't respond 2
♠ to 2
♣. If you need
two top honors from south to bid grand, there's no point in looking. South can always bid grand on his own if he has a huge amount more than he showed. So 5NT in this context should be asking for one top honor.
