judy forks will be a great match for it, they will fit fine. assuming steerer is long enough of course!
magura raceline HS33 would be a top choice. the rear brake route on the zaskar is not the best, cable stops arent all that good.
v brake would also be good. mine runs canti, they are old school, but they dont work all that well, i sometimes think about changing...
BB the thing to look for is the 73 shell 107 spindle, thats what mine runs anyway. 107 spindles are very rare these days, not a common width. if you go wider, i suspect your chainline will suffer. this is assuming you intend to run old school cranks, on mine it has 737 cranks, which do not have a very good chainline design..
