Transmission will not shift out of park and the speedometer is not working?

My car won't shift out of park the speedometer isn't working, none of my gauge's work. I had the brake light switch replaced about 6 months ago and about 4 months ago I had the starter replaced and all was fine until last night I drove to the store and the car was fine. I came out of the store, started the car and noticed my gas hand wasn't working so I tried to put it in reverse, but it's stuck in reverse. I finally pressed the shift lock button and got it in reverse and then into drive. I drove home just fine except for no speedometer no gauges. This morning the same thing stuck in park. Why? What could possibly be wrong now? I've already spent almost $2,000.00 on repairs in the last 6 months. Please give me any advice or ideas as I can't afford another mechanic right now, I've been ripped off enough by them. The last two basically overcharged me.
