I have a few problems with my car, but money is tight right now and I can't afford to take it in...so I want to see if there is anything I can do myself.

My first problem is that my car is much louder. It is very quiet until I accelerate. I have no clue what it is. It isn't urgent right now, because I can live with it. But I would like to know if it can be fixed.

My second problem is that when I start the car, if I don't accelerate right away, the car sputters kind of, then shuts off.

Also, I think a belt is slipping or something, because every once in a while when I stop at a light, the car will jump when I accelerate, and it continues for about 10 seconds.

Oh, and my speedometer just started crapping out on me. It just drops all the way down.

So, yeah, any help is appreciated...but keep in mind that I am only 17 and know nothing about cars, so diagrams/pictures/small-words will help. Thanks.
