you're on the right track. just need a chainbreaker to remove the busted link. I carry a couple sets of quicklinks, as you call them. when you damage a link, it seems to increase the likelihood of another link also being compromised. quicklinks are light. I would rather not run a shortened chain, but it can be done in an emergency.
no need for the special quicklink pliers on the trail. they're really only necessary to disengage the quicklink when you want to remove your whole, undamaged chain. to lock the quicklink after the chain has been re-wrapped onto the cogs, squeeze the brake and give the pedals a firm spin.
as far as bacon, it depends. a lot of times, it can be a permanent repair. a sidewall puncture, or a particularly big tread puncture is likely to be problematic, so you'll end up replacing the tire sooner rather than later.
a tube repair on a tubeless tire, imo, is a "just get me back to the truck" thing. I don't carry one in my regular pack---only in my Blowfish, which really only sees use in bad weather to hold a jacket, lonnnng hot ride days when I need the extra water, or when I'm carrying a folding saw for trail work. I also have a piece of heavy downhill tube to help support big sidewall tears and keep the real tube inside from herniating.
