If you intend to go between tele and wide angle a lot and don`t want to change lenses. 18/135 or 18/200. If most of your pics are normal, the 18/70 is ok and add the 55/200 VR or 70/300 VR for ocassional tele work.
Hold a six in ruler at arms length to see about what 70mm will cover. If you need less, you need a longer lens.
The 18/135 and 55/200 have plastic lens mounts that are more fragile than metal mounts if they take a hit.
Without knowing the subjects, it is hard to make specific recomendations
