practice playing regular chords, a b c d e f g, just play each one like 8 times, and go to the next one on that list.
do that until you can get it easy. also another exercise is learning a progression such as the blues progression.

just do simple chord strumming, and simple picking, and learn how to manuver your fingers on the fretboard before you try learning songs or playing tabs. tabs dont help you learn how to play guitar, they help you mimick other peoples solos and crap, they dont teach your how to move your hands correctly.
i started with power chords - the good thing about these, is you can play simple songs and get gratification from it, (just make 4 chord patterns lol) but you learn how to move your fingers from each string to the next, then i went to bar chords (a basic F note but anywhere on the neck is an example) and then i learned a bunch of regular major\minor stuff. finger picking is still beyond me. im too lazy to concentrate lol.
that is the biggest hurdle in my oppinion. once you can stretch your pinky\forefinger like 8 frets at the top of the neck, then you are getting the hang of it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
