Yes, you can frame out the hole with wood and then backfill it with dirt.
Yes, you can put dirt back in the hole before you pour. You really don't have
too much choice now that the hole has been dug.
You MUST have the frame of the concrete above the ground. If you don't,
water will collect with dirt and will rust the tower below the surface. Be
sure
to slope the concrete on the surface....a little higher in the middle and lower
on the edges, to allow water run off.
