Ton of electrical problems?

[CanadianNRG]

I hate doing electric work, all of it, but i need to get this sorted out.

-My speedometer bounces, and doesn't stay constant. It also doesn't display the proper speed which i'm going at. (I haven't noticed a pattern for this problem)

-My odometer will randomly stop working randomly, but is fixed (most of the time) when i turn off the car, and turn it back on.

-Fuel gauge is a write off. Doesn't display the proper amount i have, but is close-ish.

-When i turn on the high beams, the headlights turn off all together.

Those are the problems i have, but am not electrical wise at all. Help a man out?

Thanks
