Don't worry about your stats then. Not the end of the world given you rolled really well anyway and have max to above max in every one of them compared to pointbuy limitations.
Regarding ritual spells, you should go either silence (2nd lv) or detect magic (1st). Or if you wait until Warlock 5th before swapping your invocation over, get Phantom steed as your second one. A ghostly steed that lasts for 1 hour at a time, but moves at 100ft/round. Comes with all necessary riding equipment.
