I see two problems: 1. Did I understand right, that -"rall" changes the tempo in a single step? That’s more like “subito meno mosso” than “rallentando”, isn’t it?. 2. \set tempoWholesPerMinute doesn’t have any effect in the midi output. Is that a bug or a misunderstanding? I use Lilypond 2.14.2-1 Linux 64.
