The hooks are for a cargo cover, but it was extra cost dealer accessory until '08. None came with it. The pocket in the trunk is just that, a pocket. Some people have their CD changer there, I keep my "tools" there(Flashlight, Tire Guage, Rags, etc.) The 2 hooks between the seats are referred to as "Umbrella Hooks" I use them for Baseball Hats. As far as the RPM Hang, that is normal on Manual Crossfires. It's a sideeffect to the "Throttle by Wire" Electronic Throttle Body. A Sprint Booster will fix that "issue" if you continue to find it annoying. Do a Search for "Sprint Booster" and decide if you want one.
