I feel like they could affect each other. Though Gaara has a finite pool of energy and toph doesnt, both of their sand-bending abilities do just that- influence sand. And its the same sand you and i could see on a beach. From this standpoint, it would come down to a battle of endurance.

This applies to my battle. Both Gust and Aang can manipulate the air to the same extent and talent- it would be a matter of different means or outwitting the opponent.
