How long was tank sitting around without water?
Did you water test it to make sure there no leaks?
The older tanks did not have and did not need a center brace, so if the seals are in good condition you should be fine.
Skip the lid (use eggcrate for a cover to keep fish from jumping) and the air stone (not needed, could cause problems for some fish).
