Persistent Swatches

After you've loaded swatches from a preset library, you can make sure that library loads each time you launch Illustrator. To do that, first load the library from the Swatches palette's flyout menu. Once it's open, position the palette where you want it to appear, then use the flyout menu from that library's palette, and choose Persistent. (This also works for Symbols and Brushes libraries, but doesn't work on libraries that you've opened from another Illustrator document.)
