Test the ethernet
You can buy an ethernet tester for about $25, but you can make your own, which essentially involves wiring LED circuits to loop through pairs of wires. If each ethernet plug is connected correctly, the four LEDs light up. If any one of the wire pairs is faulty, the corresponding LED won't light up.
After everything is working, patch your walls, touch up the paint, and connect your network. You can turn excess cable--and scraps--into patch cables, so you won't waste any parts.
