Additions to your useful list:

Edit (3.) to add this link (please read!!)
http://flippers.com/vid-tips.html#discharge to your description

(17.) Use centring magnet tabs on rear of yoke to adjust picture
placement. They rotate independently and move the image from left to
right and up/down so you can get it properly centred.

Safety goggles, leather work gloves, a leather jacket, and neck
protection are highly recommended for the safe handling of picture tubes.
