The kit lens is good. I still use it in certain situations because it is versatile and it's not the end of the world if it gets broken. You're probably going to want something that's better in low light though.

I HIGHLY recommend getting the Panasonic 25mm f/1.7. It's a fantastic little lens and it's not too pricey as far as lenses go.

You're definitely going to want a tripod that is heavier duty than that, as well as a fluid head. And get yourself some kind of stabilizing solution for when you go handheld, even if it's just a cheap handle or something like that.
