That seems like a lot of lens replacement. First is your interest one that would require a lens longer than 105MM? I shot for a couple years before getting my Nikkor 70-300VR. I still find myself mostly on the wide end.
I would hate to see you purchase two lens and turn around and replace them. I think the 18-105VR would serve you better as an all around lens. Next, the Nikkor 70-300VR. If this is out of your range, the 55-200VR would be a good choice. I would not get a long lens that is not VR. Without VR you will need a good tripod when using a long focal length.
Good luck in your decision.
