Thanks for your input!
The reason I'm going with the two lenses is because they are coming in a kit for $1589.95. http://www.adorama.com/INKD90K70.html
If were to buy the lenses separately it would cost a few hundred more.
Will I not see much difference in the quality of the pictures with the Nikon lenses?

I don't know if the Nikon lenses will be better for you than what you have.
I will guess they are better than off brands and they have VR which is very nice. How much better will depend on what you shoot.

1589 is not bad for that kit.
With just a quick google price check I came up with.
The d90body going for ~899 (B&H) free shipping

the 18-105mm ~299(B&H)

and the 70-300mm ~500(new at ebay)

disclaimer: I'm no pro, just a guy getting into dslr for wildlife shooting like you.
