I don't see how using light to moderate weights will help with strength?
The "muscley" look comes from a combination of factors: genetics, body fat %, nutrition (you have to feed muscle to make it grow by eating more calories), weight work, cardio (when one is actively building muscle, one usually decreases cardio or keeps it to a bare minimum, as in the P90X series).. I lift as heavy as I can, and I look nowhere near like Cathe (which is not a look I personally wany anyway). I'm much stronger than I look!
If you want to assure that you won't get too "muscley," first, realize that it won't happen overnight, and if you see yourself going in a direction you don't want to go in, you can change your program. Then, add some cardio after your weight work (which will burn some calories that otherwise can fuel your muscle growth). Also, eat sufficient calories, but don't increase calories, which can fuel muscle growth.
