As for chords, add9s are always fun, but if you REALLY want something that will get your rocks off, try an min7(add9). Such as
----------------3-
-------------1----
---------4--------
-----2------------
--0---------------
Is that it? Yeah I think so.. Amin9(add). You can also transpose this all up and down the neck- just the top part though, obviously not the bottom root. Unless you have an extra finger. Anyways, this chord is so beautifull, not so much if you strum it, but whatever, give it a try. I could just pick around this chord for hours. Well almost.
