I replaced my hard drive and restored everything from Time Machine and now all my playlists are gone. How can I get tham back. All the music appears to be there still.

The playlists are stored in both iTunes Library.itl and iTunes Library.xml files located in your iTunes folder. They should have been restored with the rest of the iTunes folder. Restore from your recent Time Machine backup just these 2 files inside your iTunes folder, then hold down option key while starting up iTunes and select the current iTunes folder that holds both library files. If this doesn't fix it and you don't have another recent backup of these files, you might be out of luck and have to re-create your playlists from scratch. See the following articles 1 and 2 on iTunes library files.
