iCloud backups take place when your phone/tablet is locked and charging. You can also start it yourself, but the process is so battery draining that, so far, it has only worked while plugged in (and Apple suggests you do it while charging and leaving the device alone for a bit). Most successful backups happen when I didn't even intend to back it up. Once that's done, yes, iTunes backups will become unnecessary.
To add to this... to "schedule" what time you want your daily backup to happen just do a manual backup at that time. Going forward all your daily backup will automatically happen at that time.
