It can stay in that pot for several more years, so you don't need to worry there. The red things are indeed roots, but they don't indicate need t repot. It's just something they do.
After you do the leaching go ahead and use some fertilizer at 1/2 strength. Wait until the next time you need to water. Since you live in LA, winter doesn't mean as much as NY or Canada.
Don't be surprised if you get extra leaf-drop after the leaching. It's just reacting to the change and will replace the old leaves fairly quickly.
If you do the leaching about every other year your plant should do fine in that pot, in that location for years to come.
I really like Triangle Figs for their funky leaf shape and that they're nowhere near as picky as benjaminas.
