Best way to learn pronunciation in any variety of Gaelic:
Find someone who knows the language (knows it *really* -- not just someone who studied it briefly!) and pester them mercilessly, record them singing and speaking, then do what primates do best and imitate. Later, take your efforts back to your mentor and ask for help polishing the result. I was very lucky to find a true Gaelic scholar in my neighborhood; he was tremendously helpful with songs, and even knew various dialects.
Good luck!
