The Miswak can be used before or after Gargling depending on whether ones gums tends to bleed or not. If ones gums does bleed then best to make miswaak before gargling. If it does not then one can use it after gargling. In the Hanafi madhab it is stressed to make Miswaak in Wudu and not just before prayer because bleeding gums can break the Wudu. Shafi'i allows the Miswaak just before prayers.
And Allah knows best in all matters
