The rear brake shims (teflon) is sold be www.ipdusa.com Get them and have them installed. Your noise will go away if that's what it is. Overdrive arrow is that either you're in "W" mode (winter) or the P&N switch is going out (park to neutral), therefore your tranny doesn't know when to shift and indicates so on the dash. Other than that, for your loss of boost, I would check all of the little hoses in the engine bay...especially the elbows. Holes in them is a common area for loss of power.

There are several vacuum hoses in the engine bay, but fortunately for you since you don't have a turbo, you'll have less than me. Just look for little rubber hoses as small as a quarter inch in diameter running from the side of your air filter box, the left side of the engine below the thermostat housing (elbow there that often breaks) as well as another just below the ignition wire rotor (another elbow) and if you take the throttle body cover off, a plastic "tree" with more hoses. You should inspect them for cracks anyway, and if they are- replace them. I've replaced all of mine with silicone ones, but I have a turbo so that would probably be over-kill for your car.
