Thanks for the suggestions. I think I have narrowed it down to the following three choices.

62mm Close-up Kit (+1, +2, +4) for my 70-300
Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens(Fast lens plus its a prime)
with either
Nikon Wide Angle AF Nikkor 28mm f/2.8D Autofocus Lens
Nikon Wide Angle AF Nikkor 24mm f/2.8D Autofocus Lens

or I could blow the budget on one lens
Nikon Super Wide Angle AF Nikkor 20mm f/2.8D Autofocus Lens
