Earth can be use for defense : It can block away any Sand wave/attack with a wall of debris.
Mokuton has the ability to suppress Buijuu's power. Sand is not going to catch it the same way Mokuton did, the speed force will definitely sink in a bit. Its best to use it to change it trajectory then to catch it. One brother can distract Gaara while the other can fire it at will, if he loses focus on one of them, the chakra he is using to focus on one side will be weaken from another.

Like I said a wall of Doton can stop most of its Paths.
V2 power up can break bypass the rest.
