Gene- When you say the pin asssingments are incorrect are you referring to the schematic symbol or the footprint? Quite often the locations of pins on the schematic do not match the physical locations on the component. I assume this is done for convenience in drawing the schematic. What matters is if the pin numbers are correct. The footprint of the component that appears in the brd drawing is where you need to look for correct location of pins. I'm only about a half-dozen circuits into learning Eagle and I can tell you that a lot of the counter-intuitive details will soon make sense. When I first started with Eagle I ran away from it and tried a couple of the alternatives but found them no easier. The great thing about Eagle is it's nearly universal in the hobbyist world which makes it easy to use OP's circuits and libraries. By the way, another source of useful libraries are the Sparkfun and Adafruit websites. These are smaller libraries more attuned to the components we are likely to use and can save a lot of searching through the vast and confusing library that comes with Eagle.
