If each access point has an ethernet connection to a switch, just configure them as access points. Do not bother with bridging or repeating. It will be easier and perform better. Be sure to do a survey for coverage: AP placement, channelization, power, etc.
Bridging is for connecting seperate wired networks together via wireless connection.
Repeater mode is for extending a wireless signal; especially in areas where there is no ethernet connectivity available.
