Check to see if the Trek's front suspension fork has a lock-out ...otherwise you might consider swapping it out for a rigid fork.
If you can lock-out the front suspension, the suspension fork won't be as much of a PIA.
Old Man Mountain makes front racks that work on suspension forks just fine...and there are lots of options you can go with for a rear rack.
A far as weight...I am perfectly comfortable on my flat-barred Big Dummy (50lbs or so not including any load I might have) for 20+ miles. Unless you have some long and/or steep climbs (and not enough gearing to compensate), weight should not be one of your critical factors - so don't rule out that M50!.
