Alright I'd like to replace the shifters on my Trek 7200. The area where my hands contact the handlebar is split in two. The inner half is the shifter, the outer half is just a foam cover over the metal bar. That outer foam moves around and tends to slide off the handle bars in the middle of my ride. I would like to replace the "cheap" shifters with "trigger" type shifters. I have zero idea what I need or what I should be looking for. I would like to keep it under 50 bucks for parts. I'm also taking suggestions as to what would be a good replacement for the troublesome foam outer ends. What level of difficulty is involved with this type of job?

Unfortunately it's seldom that simple.
The first thing to do is to examine where your shifters and brake levers clamp onto your handlebar. Frequently they share a clamp. That means that a shifter replacement will also require brake lever replacements. Trigger shifters require a longer hand grip so you'll have to buy new grips too.
The good news is that, if you buy brand new shifters and/or brake levers in the box, they will include new cables and housings too.
Now this may be the best news yet. Stick a screw driver under your bike's handgrips and shoot a little hair spray under there. The cheaper the hair spray the better. Aqua Net is perfect. Don't touch the grips for 12 hours and then go for a ride. Chances are that will fix your throttle grip problem.
