the best way to start is to find a song you really like and just try to play that song. the only thing that's hard at first is the transition of your fingers from song to song. once you are able to play one song completely you'll be able to get the hang of it then you can start playing other songs. on the strumming part, try to sing the song to get the beat and the right strumming.
other guitar skills will come naturally in progression as you play like plucking, doing riffs and other stuffs like that. well, that's the free way of learning to play the guitar.
but if you have lots of bucks to spare, there's always yamaha.
