You won't get far (at least not very fast), without learning general music theory and guitar theory. Start there.
Learn your basic open chords.
Learn barre chords.
You won't be able to play and sing at the same time for several months, trust me.
That. Theory is so fucking important, it can't be stressed enough. Wikipedia has some really complete and extremely useful articles on music theory. I used those almost exclusively to learn chord theory, and I still use it for reference all the time.
Actually, with open chords, singing and playing is really easy. I could do it like a day after I learned the major open position chords.
Also, as much as barre chords fucking suck to learn, they're so awesome. There's so much you can do after learning them, especially once you start learning minors and 7ths. Just remember that they're a movable form, so that no matter where you play the position for one barre chord on the neck, it's the same everywhere. If you've got an electric guitar, lower the action a lot so that it's easier to get them. And yes, the muscle in your palm that controls the thumb will hurt like a motherfucker for about the first month or two of working them, it's normal.
