Firearms = Todd, Willie, Kate, and Carl.<br/><br/>Todd had basically made it a group of 2 people per gun.  Speed doesn't count for much since no one is going to be running around in the dark with zombies around, and slow and steady usually equates to quiet and safe.<br/><br/>A smaller group of Caitlin and Willie would be easier to get in and out of a store and less likely to be noticed true, but it'd basically be Caitlin getting the supplies with Willie covering her.<br/><br/>I don't know if what Caitlin would need is in a public library, or if there are Bible's in a library.  As for the holiness of a Bible, a priest can simply bless it and make it holy.<br/><br/>I already see Carl dying to a crowd of zombies while he's Bible thumping.  Poor guy.
