Don't worry about bulking up - women don't often get really huge muscles unless they're body-builders and take all sorts of supplements or steroids. If you're a normal girl, you'll just get nice, lean muscle from working out.
The best equipment is just free weights (dumbells). They make all your muscles really work together, instead of isolating one little spot like machines. They improve your control and balance because you have to make sure not to drop weights or swing them around or anything.
