2006 Ford Taurus Rough Idle w/ vibrations and clicking nois

I have a 2006 Ford Taurus with around 83k miles on it. I am having two issues that seem to be worsening. First issue: Whenever my car is idling (the longer I have been driving, the worse it is) or driving at very slow speeds, the car makes a moaning noise from the engine and harsh vibrations go through the car. The sound almost sounds like the car is going to stall, though it hasn't yet. Second issue: Whenever my car is moving, even at slow speeds like 5 mph, I hear a clicking noise from what sounds like the front tires on both sides. This has been getting worse. It started off when driving next to a car, wall, building, etc., but now you can hear the noise in semi quiet environments. Its about a 4 on a 1-10 scale. Any thoughts? If you need additional info, let me know. Thanks!
