Hi bud,
The clock could just be a glitch & would try removing the cluster & disconnecting it for a few mins. - on comand vehicles the time is synced from the comand which gets the time via GPS. Otherwise could be an internal fault which may mean a new cluster. Would also be worth checking the coding to make sure it knows it's a comand vehicle but you need star diagnostic tool for this.
Creaking could be springs rubbing rubbing on lower arms- check for signs of fouling marks on the springs where they sit in the arms.
Could also be the rose joint in the hub, a common cause of creaking
