Hi Scott:
That is a pretty good list for starters. Don't know how much time you have but a visit to Hobby Lobby will earn you the instant joy of hearing Gospel Songs played in such a variety of styles without the vocals... you will be blown away. Marketing 209! These folks are brilliant.
Then, there is option two: Visit any nearby church and see if you can borrow one of their hymnals.
Gary is always right! Best of luck with this gig. Would love a front row seat.
All the best, ----Dave Rice
