it is do-able. just check the seatpost sizing on ur trek vs the shadow. check the bottom bracket specs too, make sure ur bb is compatible or u have spacers if needed. also make sure ur current front derailleur is compatible with the shadow (clamp size, swing and pull). the shadow is a dual pull, just make sure down swing fd.
other than that u shouuld b ok...
i went from a rockhopper and transfered everything over to a reken frame and needed a new seatpost (and fd, but didnt get one since i went SS). i wish my fork had a longer steerer but its ok for now.
i only had basic tools (bb tool, etc) and no stand. the only tool i didnt specifically have was a headset removal and installation tool. i just used a rubber mallet, wood block, big flat head screw driver and a very careful hand.
have fun!
