Lots of Check Engine Codes! PLEASE HELP!

I have a 2005 Jeep Liberty with 126,680 miles on it, the 3.7L V6 and Automatic transmission. The check engine light came on, so I did the "key dance" and it came up with a mess of codes! Here's what it gave me; P0203, P0201, P0204, P0205, and P0174.
Any ideas of what could be causing this? Any help would be appreciated! =]. Thank you!

I had P0203 code coming up on mine and AutoZone told me that I needed to replace Coil #3 .So I did and I went ahead and got plugs to change them out why I was under the hood and I put new gaskets around each old coil cause coils aren't cheap. Now my truck better then it has ever ran even better then when I first bought.It still had regular
Plugs on it Don't know if that help but I hope so.
