Also, I do believe that Merlin somewhat lost sight of what his true goals are, in his pursuit to protect his best friend, and king.

That's understandable. Merlin's life centred around his belief that he was destined to protect Arthur and guide him to become a great King who would unite the land of Albion, restore magic, etc. It was his purpose in life for a good nine or ten years by this point. Because he wanted to believe that Kilgharrah was right about his destiny with Arthur, he also believed what he said about Mordred, even though he fought it at first. He truly believed that Mordred was a threat and that saving his life would mean Arthur's death. He couldn't advocate that.

''On a side note, there is also the whole "Once and Future King" thing, which is left completely open-ended, and untouched by the end of this show! On top of all of the other questions...''

Perhaps the clue was in the name. Arthur is supposedly the Once and Future King, not the Once, Present and Future King. Maybe he was a King in a past life, and is to do great things as a King in a future life but Kilgharrah was too premature when he claimed that Arthur was destined for greatness in this life. Maybe Arthur wasn't yet ready for his alleged destiny, which may even have been derailed altogether since Merlin has left him to rest in Avalon instead of being reincarnated to continue his destiny.
