That's a lot of equipment to take on as hand luggage. As already mentioned, be aware of carry-on restrictions for the airline you're flying with.
If you need all that gear for work, I'd probably want to put everything in a decent flight case and put it in the hold, otherwise I'd think about whether you really need all that for your trip. I used to travel with a similar sized kit, but now I don't even take half of it.
Anyway, if you do need to take it all with you, I've managed to fit the following in a Lowepro Vertex 200 AW as hand luggage:
5D & 7D bodies
5 or 6 lenses with hoods, one of them a 70-200 f2.8
Off-flash cable and shutter release cables
Teleconverter & extension tubes
5 77mm filters, a few step up rings, and also a UV on each lens
There are attachment points for tripods and modular pouches. I can't recall if I used them or if I had another bag with me to put the tripod in the hold.
The Vertex 200 suited my needs just fine. Quality wise, I'd say it's on par with my ThinkTank bags, and there are plenty of pockets and dividers. The harness/straps are well padded and pretty comfy, but you will notice all that weight when you're walking to your terminal! http://store.lowepro.com/backpacks/vertex-200-aw
ThinkTank's bigger bags will likely be as good or better than LowePro, but something like this may also be of interest:http://store.lowepro.com/backpacks/pro-runner-x450-aw
