All those points sound good. I too would like a writable journal for the PC version so I can remember things better since my memory isn't that great at times.
As for "dumbing down" the game, I don' t consider having an optional difficulty slider dumbing it down. It's there for anyone who chooses to use it. An example of the game being "dumbed down" is like when they put in quest markers and it not really being optional (quest journal entries weren't descriptive enough on their own to know where to find things/ destinations). Morrowind had a difficulty slider of sorts, so I don't know why they would take it out for Skyrim.
