I'd look at the UD10 or UD20. The UD10 will hold all that without a lot of space to spare. The UD20 is a little larger, I just bought it this afternoon. It can hold my E-510 w/ 12-60 attached and another lens of similar size. A little more if you put the camera in the front pocket. I put the FL-50R in one of the side pockets. They are very well made and don't look like a camera bag. That's why I love them. I also have had a UD35 that's been through a lot and still is looking great. Both are smaller than the Changeup mentioned earlier. My only recommendation may be the replace the shoulder strap with something more a little more comfortable. I haven't carried mine around much yet though and your kit is much lighter than what I'm putting in mine by maybe 2 pounds.
