Depends a bit on the goals for the water changes, but I have the same tank and similar sump and do a 40 gal WC every two weeks, or thereabouts.

It depends on your needs. Some folks don't do any water changes. If their system needs nutrients they simply dose them, and their waste nutrient export is efficient enough to eliminate water changes all together.

A good rule of thumb when starting out is 10-20% weekly or bi-weekly. Yet again it is dependent upon the need of your system.
