If you are very sure you want to shoot landscapes, animals and insects, you'll GENERALLY want:
-A UWA zoom (Canon 10-22, Sigma 10-20 f4-5.6, Tokina 11-16 f2.8, Tokina 12-24 f4)
-A tele macro prime (Tamron 90mm Macro, Canon 100mm f2.8 Macro)
Depending on the types of animals you shoot, you might want to get a 70-200 also. If you are very sure of what you want to shoot, you should jump straight to the better lenses and not play with the kit lens.
A good way to judge what lenses you need are to look at the focal lengths you shoot the most on your point and shoot (look at your "picks" and see the focal length). If you are shooting a lot at the wide end, you need a UWA. If you shoot at the tele end, you need a tele zoom/prime. If you don't shoot at say, 50mm, then you don't need 50mm. Just stating an example here, everyone is different in terms of their style, so get the equipment that suits your style. Don't just blindly get the lenses people recommend, if the lens does not fit your style, you'll end up wasting money. That's why take my recommendations with a pinch of salt, look at your current photos and see the kinds of focal lengths you like to shoot at.
