Yes, "brifters" are the integrated brakes/shifters. They are very nice and usually work very well. I have them on my road bikes.
Most people do not prefer them on touring bikes. On a touring bike you want something that is simple and can be fixed out on the road, if need be. If brifters happen to stop functioning out in the middle of nowhere, they lock up in one gear. You might not be able to fix them or find a replacement for them while on tour.
Bar end shifters work by pulling on the cable to the derailleur. It's simple and if it breaks, it's easy to fix. They will also work with any type of derailleur, brifters are more picky.
I have bar end shifters on my LHT, but I moved them up to the handlebars. Nifty.
I got some little devices called Pauls Thumbies that fit on the handlebar and the bar end shifters attach on to them. I also have cyclocross brake levers on the top of my bars too so I can shift and brake from the top of the bars. It all works great. The Pauls Thumbies are expensive though - $50. The Boy is quite the bike mechanic and set up all this stuff for me. A good bike shop should be able to do this too.
Here is my LHT on a tour in 2008:
