you would need to change the fork and wheelset to add disk brakes to the front.

I dont think you can add disks to the rear if there is no mount on the frame itself.

You will not have greatly improved braking capabilities by doing this.

just replace your pads with some kool stops.

your best solution is to bring a change of clothes to work w/you, get there 15 minutes early so you can change and clean up. dont forget the antiperspirant/deodorant.
