on the brake light problem, where the brake pedal is follow the peice of metal a few inches up and you should see a small push button type spring loaded switch. that is called your brake lamp switch/neutral saftey switch. it is usually held in place but a few screws and has a molex type connector providing power. you can get those at auto zone and oriellys usually for a couple bucks. swap it out and your good to go.
edit, oh and pick up a new transmission while you are there =)
