There are more learning resources on the BBC site, e.g.
An Litir Bheag for relative beginners and
Litir do Luchd-Ionnsachaidh for advanced learners. You can download MP3 files and the corresponding text as PDF. At
Aig Cridhe ar Ciùil, you can listen to Gaelic music; written lyrics are provided. I always found music a very convenient and fun way to practice my pronunciation, so give it a try.
