From that perspective, I'm in agreement with you, as the standard dramatic fake-outs often impact my enjoyment.
But this stuff you are bringing up all gets a pass from me. The Ouija board for example. If you were in that guy's position with the paralysis and the bell and all that, wouldn't you want there to be a similar device around? Obviously someone is paying for Gramps to be housed in the facility. I don't see a problem with that payer saying to the staff, "Make sure there's a Ouija board around. Gramps needs one." Maybe it's his board, and they brought it with him along with his clothes.
I'm the guy who gave up on Lost because of a problem similar to what you've been describing, but so far the 3 things you've criticized don't seem to be problems. If you find something out of place that I can't rationalize, though, I want to know!
