First, confirm that it's finished. It should be, but if you had a lot of data to back up and/or a lower-speed bus, it might not be. It might also be working on an update if it finished your initial backup. If you're using Time Machine, by default it places an icon on the menu bar in the shape of an analog clock face with an arrow encircling it. If it's in the process of backing up, there will be two arrowheads, or if that's too hard to see, you can click on the icon and the pull-down menu will either display the date of your latest backup, or "Backing Up" with a progress indicator.
If the drive isn't chewing on anything, then you can decide whether to leave it plugged in. If you leave it plugged in, it will automatically update itself on a regular schedule, so that's best if you don't have any reason to unplug it (like if you need to move your computer, or you need the port for another device).
If you do decide to unplug it, eject it from your system first. Go to Finder, then there are two ways you can eject an external drive: In a Finder window, on the left bar, below the list of your Favorites, the next category is Devices, and any connected drives are displayed. Select your backup drive and press Command-E, or choose Eject from the pull-down menu under File. Alternately, an icon of the drive should appear on your Desktop, and you can drag that to the Trash. It will grey out first; wait until it completely disappears before physically unplugging it. Then, best practice is to plug it back in when you can, so it can resume regular backups.
