Talking Some Basic Questions.

Ok so I have a couple of questions for you guys.

1. When the truck is started it idles very high for about 30sec then goes to a normal RPM. If I put it in gear when it is idling high it jerks very hard. What causes this and how can I fix it?
2. The overdrive light on the shifter column does not turn on when the over drive is off. How do I replace that?
3. If I took the cat and resonator off the exhaust and put a high-flow cat and a cheap glasspack on there should I be getting better gas mileage?

Thanks in advance. I’m kind of new with this so bear with me

1 is normal, my truck does that too. Blip the throttle, and it should come down. I can't help with number two, but for three, yeah, you should get a little better fuel economy.
