I have the Benro Carbon Fiber C1681TB0 Travel Angel Tripod Kit C1681 +B0. It is only 3Lbs and very small and has an Arca Swiss type ball-head with is fantastic. Highly recommended. You can also look at the 1691 which has five legs instead of four. This line of tripods is called Transfunctional, meaning one of the legs detaches and becomes a monopod, which is sweet!
You can also look at their zero and two series, although I would not recommend the zero for your gear list.
You can buy these local from B+H but can save a few bucks going to eBay if you can wait. I shot mine with my 40D and 17/55.2.8/IS or 70-200/4.0/IS with no issues. I also have a Gitzo 2531EX, Markins M10 and RRS clamp - although far more stable than the Benro, it is much longer and weighs a couple of pounds more.
Here is mine on eBay:http://www.ebay.com/itm/Benro-C1681TB0-Travel-Angel-Tripod-Kit-C1681-B0-T027-/300559215496?pt=US_Tripods&hash=item45fab9ab88
Here is the whole series (minus mine for some reason) on Benro's site:http://www.benrousa.com/products_catalog_TransfunctionalTravelAngel-CF-TwistLocks.html
Here is the same series in aluminum:http://www.benrousa.com/products_catalog_TransfunctionalTravelAngel-AL-TwistLock.html
You could always get the Cadillac and go with the Gitzo 1541T and Markins Q3T or RRS BH-25, it all depends on how much you are willing to $pend!
