I'm going to buy the Nikon D7000 with the following lenses?

I'm going to buy the Nikon D7000 with the 18-105 mm lens… The 70-300 mm lens and the 50 mm f/1.8
And I was wondering if I should buy any lens filters, or does that really make a difference and anything else that I should buy. Thanks

And I'll be getting the SB-600 speedlight. Is that one okay or is it better to get a more recent one

Is there any reason why you want all that stuff at once? After all, you might find out that you're more into landscapes and could make better use of an ultra wide angle lens than the just as expensive 70-300 telephoto one.

Get UV or clear glass filters for all your lenses, as protection. A circular polarizer also is very useful for landscape and architecture shots. As with lenses, buy quality filters, not cheap ones. Hoya offers a very good price/performance ratio.
