Quick layout advice.  I'm going to go with James's suggestion of brown/black imitation leather with copper lettering.  LBC just told me that for their default computer font, it all has to be the same size font (I had been used to the title being larger than the rest).  So, I'm left with

or 2) Putting it horizontal on the spine:

The only thing to note is that a few of my books will have multiple short titles bound in them, so the horizontal view would have to look like something like this:
