When starting from a dead stop I hear a growling/squealing sound. Seems to be on the belt side and in that area. Once I get going the sound disappears.

If it's the sound I'm thinking of you might just need a new belt or a pully. Typically water pump going out sounds like you have a turbo winding up and steering will growl.
I would start with a belt. While removing it feel how much tension the tensioner has on it, on the 3800 egnine they have a stiff tensioner(sorry I don't have any specs for how much) After you get the belt off you can look at all of the pulleys and spin them to see if the bind or look for stuff stuck in the grooves on the pulleys.
It sounds to me like the belt is streched. I would not recommend one of those gator back belts, they seem to make more noise sooner than a good v notch belt. But thats just my opinion!
Squealing, like a belt? I've found that the alternator belt has to be super-tight or else it squeals. It's a pain in the **** to torque the alternator sideways enough to tighten the belt.
If it is a belt, you could also buy some belt dressing spray and see if that helps. It's pretty cheap stuff per can.
Try removing the belt and turning each pulley by hand. If everything is smooth and free, with the belt still off, drive down the block once and see if the noise is there (this will eliminate all rotating accessories on the front). If you hear the noise, then there is a problem deeper inside. Oil pressure is good? Dont' forget when doing this, you will have no power steering, so be careful.
You have a loose belt on the A/C. On most new cars that is one big belt that drives everything on the car. If when you look at the belt on the grooved side, do you see cracks on the grooved part running across (from side to side) on the belt? if so, it is in bad need of a new belt. A new belt should stop the squealing noise. While you are replacing the belt also check the belt tensioner to ensure it is in good working order.
