First, get a plan, budget and set some goals (reachable). Don't simply build your car for a specific vehicle to try and spank. That's high-schoolish. And it sounds as if you're in way over your head if you have to ask what you should do first. Not saying your questions are invalid because you got to start somewhere, it only implies that you're not exactly ready to take on the whole modification process without first learning a lot more about what you want it to do to your car. You'll have to live with your car long after you win or lose.
Beating a Ram truck isn't, and should NEVER be, a goal. Set your goals right and it'll be just an aside. There's better goals out there to shoot for.
Oh, and Santeen- quit being a troll.
