My personal preference for touring long distances in short time is to eat a large breakfast, then ride pretty much non-stop until the day is done. Gas stops are Nascar style, with maybe a protein bar. I find if I stop, grab a lunch, take a break, I'm more tired and unfocused afterwards. If I'm really tired, an energy drink of some sort keeps me going. Advantage of not taking extended breaks is it saves a lot of time. Stopping, grabbing a lunch (even something super quick like McDonalds) will easily chew up 30-60 minutes of riding time. This what works for me, may not work for you.
As for your schedule, 1000km in 10 hours is doable, but hard. Near impossible if you intend on taking brakes as you describe. 1000km in 12 hours is more realistic. Doing that sort of mileage continuously for four days will beat you up really bad, expect to be completely spent and unable to do anything after the four days.
For tools, the stock FZ6 tool kit (if you have it all) has everything needed to adjust the chain; two wrenches to loosen the axle and two ten mm's to move the adjusters. That's '04-06 models, can't remember if '07+ is different. I would add a multitool (Leatherman Wave is my favourite), zip ties, electrical tape, that will get you through most roadside fixes. A tire patch kit isn't a bad idea, though I personally have never needed one on the road (two nails in ~150k km of riding)
I would add a camping chair to your camping supplies. My fake Helinox ($40 from Sail, can be bought from Amazon etc.) is one of my favourite camping things. Packs up pretty small (~12"x4") and is crazy comfortable. After a long day riding, you'll want something comfy to sit in and relax. Not realistic for you since you already have a stove, but I like my MSR Dragonfly. Runs off regular gas, so the gas canister acts as a fuel backup. Saved me this past weekend, that extra litre was the difference between me being stuck in the middle of nowhere NH and puttering into a gas station.
Another thing is a warm set of baselayers. I have the Under Armour infrared or something. Packs up small, doesn't add bulk, and big increase in warmth.
Addendum: Rok Straps are the ish for strapping stuff to your bike, used to do the bungee cord thing, but it's a night and day difference.
