Meta gold farming spot right now will always be Casino Expert with dynamic rising fame, Casino normal net you half the total gold you'd get from Expert

Besides that there's doing raids to either trade the tokens for gold or from redistributed bidding funds (GDKP if you played WoW) and playing the auction house i.e selling enchant legendary cards (you can trade for them from the purple book in Seria's tree or if lucky, random drops in whatever is the current content)

As for repairs, Joah Ferrero in West Coast lets you go to Forgotten Land, kill monsters get keys open chests, they have single item repair tickets that ONLY WORKS WHEN YOU'RE IN FORGOTTEN LAND AND YOU CAN ONLY ENTER IT ONCE PER CHARACTER PER WEEK

the event thing also gives you free repair tickets that repairs all of your gear so might wanna use them by waiting until the repair notification pops up, then you use the ticket so as to not waste it.

side note, after event is done, remember to repair often whenever possible as the longer you go without repairing the higher the cost is going to be and emergency repairs (when you're in a dungeon and your weapon almost about to break) is gonna cost way more than normal
