Noob here with a load of questions about an older bike.

Ive been riding a short commute to work that is mostly flat so I haven't done much in the way of upgrades. But now my commute is going to triple and include a massive couple of hill climbs. I'm looking to drop weight if possible. Other than the wheels anyone know if its possible to replace the front fork and handle bars on this beast? Ive had trouble finding tech specs on this model. Any help is greatly appreciated.

Thanks for your time.
