from a focal range point of view the only lens that adds to what you already mentioned is the 70-200mm.
the 24-70mm would definitely outclass your 24-105 and be much sharper but it wouldn't really offer too much of a new point of view for you. the 85mm from what i have seen is a spectacular lens but i think you can still get a look in a similar ballpark using the 50mm you already have.
the 70-200mm is also a very special lens but it offers great versatility. i would get that one if i were you.
if i were starting from scratch the two lenses i would get first are the 24-70mm and the 70-200mm so that i had a good range across focal lengths with the highest quality available for zoom lenses. i would then start addressing lenses for those special eye catching looks that you can get in fast primes. finally i would get specialty lenses such as a 15mm fisheye or the 100mm macro.
get coverage first then go for "the look" then go specialty. my 2 cents.
I agree with this, I think the 70-200 will open more doors for you first, and if you need wider coverage you can reach for the 24-105 until you've saved up another 2k to upgrade to the 24-70 II.
