My general experience with premade libraries is they often aren't exactly what you expect, and you should always always double check them against a real part when possible, and carefully check it against the datasheet if not. Also, a pair of calipers to check the diameter of pins helps a lot too. I'm having to respin a board because I didn't do this.
Oh, and Newark has Eagle libraries for many of their parts since they partnered up with/bought Eagle.
