Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .
Use #10 copper.
#6 bare copper wire.
