<< Am I making good progress? Faster than other people? When can I be expected to play the really hard songs? >>
Sounds to me like you just want quick results, and don't *really* want to learn music, or the piano. Who cares if you're learning it faster than other people? Who cares what songs you can play? If you've been playing for a few weeks, expect a few years (at least) to be able to play any half way difficult pieces properly. Learning to play the piano, understand and read music, etc., is not something you get from a simple "for dummies" book.
<< I am reading from both clefs, and doing lots of chords. Damn, my left hand! >>
If you're not using your left hand, you're not reading both clefs.
