get skype, or xfire, and ill explain in detail how to take care of distorted/blurry mapped faces. in short, when you use the modifier "unwrap UVW", there is a dropdown menu on the right column called "map parameters". under it, there is a button called "quick planar mapping". select your face and click that button, and your texture will be mapped out to avoid distorted faces. you may have to choose through one of the three axes X Y or Z, if the "default option doesnt give yo the effect you wish for.
