How can I stop all tracks on an album playing automatically?

Uncheck the songs in iTunes. Change the sync selection options so that you can include unchecked songs. When playling an album or playlist that only contains unchecked songs you should find that the iPod pauses when each track completes and you can manually select the next track to play when ready.

An alteranative approch would be a playlist with long silent tracks between each backing track, and you skip past the current silence when you are set.

1. A further alternative is to set each of your own songs (in your iTunes Library) to Skip When Shuffling. Since you already have these songs in one album, you shouldn't need to create a Playlist for the album, but you can if you wish.
2. Sync the changed songs to your iPod. If you use Sync to manage your iPod, then a simple Sync should effect the changed songs on the iPod as well.
3. Now, on the iPod, select Settings/Shuffle>Songs. Do not use the Shuffle Songs on the Main Menu, this trick doesn't work if you do. You have to set shuffle on the Settings menu.
4. Now, on the Albums menu, navigate to your album and select the first song. When it ends, the iPod will stop (because every other song in your album is set to skip when shuffling.
5. At your leisure, you select the next song that you want and start it playing. When it ends, the same thing happens, the iPod stops.

If you created a Playlist (in step 1.) then at step 4, navigate to that Playlist and start your first song playing. Again, when it ends, the iPod will stop since every other song in the Playlist is set to skip when shuffling.
