That's a lot of stuff, and it looks like you may have some duplications, for example the zooms, so you may want to consider more than one bag, one a little smaller than the other perhaps. Put the stuff you use most in one, and then a larger one that either takes everything or just the leftovers. I would probably just carry the tripod, IMHO strapping a tripod to the bag makes the bag hard to handle and gets in the way of working with the tripod. A lot depends on how you want to work though, if you're carrying a bunch of gear to get to a location where you'll set up for a while a pack with the tripod lashed to it wouldn't be so bad. In urban settings with a shoulder bag, it's a problem.
I recently bought a Tamrac Summit backpack bag, for my view camera. It's smallish compared to many backpacks but it could take the stuff you've laid out, if you add some of the accessory pockets they make. I've not used it very much as yet, but so far I like it a lot. It would let you a "bigger/smaller" approach by using it with or without added pockets.
Generally I prefer shoulder bags, but for what you've listed you would need very sturdy shoulders. You could consider a Domke F2 which is probably a little small to take everything, especially to include the iPad, but might be good for the F4 and several lenses and misc. stuff.
They also make larger ones. Lowepro makes some nice shoulder bags too, my oldest bag is a Lowe that houses my Nikon kit, I forget whch model but it has lasted through much use and abuse, it's about the same size as the Domke.
I've been looking for the "perfect" bag for a long, long time. So far, all I've come up with are several that work pretty well. Perfect for me would be one that can take everythng I own, weigh no more than 1 pound loaded, fits under an airline seat with room for my feet, and can be laid out so I can reach anything I need by feel, plus doesn't cost more than maybe 25 USD. I'll probably be looking for a long time to come
