Interesting list, I both agree and disagree. A couple of things:
Long weapon lists: Stick 'em all in there! As long as there are no traps for inexperienced players, it makes a lot of people very happy to see a page full of weapons in the PHB. Let's not deny them their fun.
Spell components: Since only expensive components need to be actually managed outside of a Component Pouch, this seems fine to me and is usually first on the agenda for house-ruling anyway. I might not do that this time, just to see what happens.
Identifying magic items: I will be house-ruling the "fondle it for a Short Rest and know what it does" rule. This is a 4E hold-out that I never liked in that edition either.
Advantage/Disadvantage not stacking: To me, as someone who has DM'd hundreds of 4E sessions, this is a direct and appropriate response to the horrible bonus-hunting sweep that would circle the table every time someone rolled a number where the result wasn't immediately apparent. Collapsing stacked bonuses into a more simple "You have a advantage here, sir" is great design. This is the basic game after all. I think it's exactly the right call.
Charge: I will wait and see on this one, as it depends on the interactions between attack ranges, movement, terrain, action economy, and other factors, plus is really only needed on a battle-mat. Since the basic game doesn't need a grid, Charge becomes less important.
Death Saves: When I read your comment about Death Saves and Con bonus, I mis-read it at first to think that you meant your Constitution *score* should be the save value instead of the normal 10. Now that I've thought of that, "Roll equal to or under your Con score to make a Death Save" seems like quite a fun house rule.
