Anything with tablature in it is good if you're just wanting to learn songs and can keep up with the rhythm. If you really want to grow your skill, I would suggest learning to read music as well.
If you're just beginning, learning all the "common" chords is a good place to start. But the most important thing, as had already been mentioned, PRACTICE. If you don't apply yourself and take time to work on your skill, you'll never be any good.
