Took it in to the shop yesterday and told them to check the idler pulley first. You guys were right on the money. Also replaced a busted motor mount which I was expecting based on what I've read here about movement in the shifter. Front brakes were nearly gone so I got those done. Throw in a pair of wiper blades. Everything OEM. $1,188. I love my car, so it's all good. Thanks for pointing me in the right direction!
