Check out the collection of piano pieces on here, I'm sure you'll love it! I'm currently in love with the sheets of Superman by Five for fighting, it's so good and unbelievably, rather easy! Just click on the link (if it's a link), right click, "save target as", and voila! It'll be in pdf format so you have to have acrobat reader installed. :)
I love this site a lot. Not only do you get the chords, you also get to learn tips on how to strum properly so you get the correct melody. Plus, you can choose from different versions so you'd know which sounds best :) One tip: try to have your guitar with you while checking the site so you can try out the piece already before printing because like I said, there are different versions and one version is better than the other so you have to know first.
Have fun creating your own collection of music sheets girls! Time to unleash the ultimate rockstars within! haha! :)
