If you haven't already try the
http://www.bbc.co.uk/irish/ site, it also has a course called Gíota Beag which I first used when I started and it's very good and will help you get the blas your after.
I wouldn't focus in the pronunciation of everything to the nth degree though, pronunciation is something that will come naturally as you go along, the most important thing is constructive learning in my opinion and using what you have and not being scared of mispronouncing or mistakes, fluency comes from that.
And it's true, Bríd's voice is great
