First practise power chords (the beginners best friend) then mabey move to bar chords and open chords.
Most songs which have been tabbed on mxtabs or whereever are in power chords so thats usually a good way to practise.

Once you have a pretty firm grasp on playing chords and keeping in time with yourself. You could move to to leaning a few scales, more specifically the good olde pentatonic scale. Its probably the most simple and useful. Also it gives you a slight intro to the way the same notes occour up the fret board.

If you wanted to be fancy you could learn all the places you can play it up the fret board but thats kind of advanced if you are only just starting to learn.

umm thats all i can think of. Once you get quite good its fun to play along with songs to practise your elite solo skills.
