The CPU is really weak. 1066MHz RAM is slow. You should use the DVD burner, HDD, keyboard, and mouse. That saves you ~$140.
Looking at your wishlist, I see the 550Ti. It will do pretty well in GW2, but move to more intense games, and it won't do so admirably. For the same price, you get the 6850 which is a lot faster than the 550Ti.http://www.newegg.com/Product/Product.aspx?Item=N82E16814102908
The PSU is good, but you can definitely get a more reliable one, and cheaper!http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028
