Back to the brakes... That is a significant difference in pad wear from the inner to the outter pad.
Make sure the caliper guide pins are thoroughly lubed. Also did you inspect the caliper piston boot for rips?
I have done (myself) the brakes a total of 3 time. I always get consistent wear, within 1mm, for the inner and outter pad (front or rear).
Seems that there may be some others factors going on here.
The fluid can range in color from green, to orand, to reddish, to outright brown. As long as there isn't any signs of water, then you are OK.
Everything was fine with the brake assembly (boot, piston, etc). In my experience there is always one wearing more than the other (which is why they tell you not to rely on the wear of the outside/visible pad), but I've never seen that much of a difference.
