Uncle Jacque,
There's a whole thread devoted to My Jesus, I Love Thee. Which reminds me that I was supposed to be tracking some additional words down.

Your 'Zion' is by Thomas Hastings. In the 19th cent. it was often used with "Guide me, O Thou Great Jehovah," before that really well know Welsh tune made everyone forget the other tunes they used with it.

Belmont is a really familiar tune. You should not have any trouble finding it in your books.

You can find Midi's of the tunes you've got from Southern Harmony (Delight & Disciple) in the Online version. Disciple should also be in some other hymnals. It sounds familiar to me as a hymn, not a shape not tune. Delight is also in Sacred Harp. I found one online recording: Go to the Real Audio at the top of This page. Delight starts just shy of 2:35 (2.5 hours in). The Sacred Harp portion of this program starts 30-40 minutes in.

After singing the music the way it is in this recording, the Boston Camerata recording is not as satifying as it used to be for me. If you like "Trav'ling Home" you'll also like their "American Vocalist."

Another place to hear the old hymns is at Pilgrim Productions
