Filipino for Everyone : Mastering Filipino through English Book

If you want to learn actual Irish as it is spoken and not the standard (which isn't spoken -anywhere- except by non-natives), this is one of the two best books. This text teaches Irish as spoken in Cois Fharraige, in the Connemara Gaeltacht. It is very thorough and can come off as dry and academic, but is still one of the best resources for actual Irish if the learner is willing to put the time in.

For Munster Irish, the 1961 version of Teach Yourself Irish cannot be beaten. It teaches West Cork Irish from native speakers, and can be found online (it's out of copyright) with audio.

If you wish to learn Ulster Irish, I don't know many beginner resources for you, but I have heard that Buntús na Gaeilge, offered free on Dr. Barbara Hillers' website, is a good start.
