As for chords and stuff, you could get yourself a tutoral book (which I never found particularly useful)though it might help with holding the guitar, strumming etc. I prefered learning by trying to play songs I liked. You could go to say http://www.guitartabs.cc/home.php for example and look up the chords for a favorite song. http://www.cyberfret.com/chords/changing/index.php is a nice site on chords and how to learn playing them. Should be enough there to get you started.
Hope this helpful. If you're still having problems give us a shout, AndyP
