I have a similar situation, a Salsa La Raza, and my eyelets were obscured by the hub I use. I went with a Tubus Fly rack, it is very light and has 3 attach points, the top one being the brake bridge. I initially used P-Clamps to install it, but after breaking several I bought the Tubus clamps, the hold better and hold the rack away from the frame more, allowing for better clearance.
The bag I use for lugging my laptop is an Osprey Torque, it has simi-ridig sides, and with a few carribeaners through its lash-on loops, worked well as a pannier. Fully loaded though I would end up kicking it. I bought some replacement parts for Ortlieb panniers and mounted them, best panniers I own now.
