You will need a set of brake levers, a set of barend or index shifters, new handlebars, brake cables and housing, shifter cables and housing.

I would experiment with your position first.

1) Handlebar tilt. Loosen the bolts that hold the handlebar in place and pivot it up or down.

2) Stem. I would get a new stem if the above doesn't work. For now, I would get an adjustable stem.

3) I would move your seat a little bit forward. Justa teeny bit.
