Should I use sand or 1" gravel to fill the low spots?

You can use anything reasonable that is available and cheap.
Gravel, sand, base material or earth removed from another
site prior to building, etc.


*How much top
soil should I put on top of that to grow the grass in?

4" when settled down should be sufficient



*Will the new

It won't wash in, but it will compact down. How much
to allow for depends on how deep it will be and the
exact material. I'd try to partially compact it a bit
when putting everything down, starting with the fill.




*If I figure out how
much fill is needed in cubic feet, how does that relate to tons of
stone/sand? *Some one told me fill is sold by the ton rather than by
the yard.

Whoever is supplying the material will be able to tell
you the approx conversion.
