A few corrections and notes:
-You should mention that Link, Toon Link, Lucas, and Samus cannot grab airborne people.
-Grab-armor is not universal; Olimar doesn't have any.
-You can make people go into a footstool animation while they are grabbing, too. I think it's also important to note that footstooling someone while they are in hitstun stops all knockback.
-I'm almost positive Zero Suit Samus has a wall-cling. You also forgot to mention that she has a crawl.
-Uh... I'm pretty sure super-armor and heavy-armor are not universal. Is that a work-in-progress?
-Glide tossing is not universal; Yoshi can't do it.
-I believe that Double-Jump Cancel Item Throw (DJCIT) is an important technique to mention since it applies to a few characters.
-You should make a note that Zero Suit Samus' n-air and Olimar's f-air, b-air, d-air, and u-air can clang with other moves.
-There's nothing on momentum-canceling. Did you intentionally exclude it?
-You should mention that Yoshi's powershield does not allow him to act out of it immediately; he still has to suffer through the shield-drop animation. Speaking of which, you should add shield-drops in general (and how characters can still spot-dodge during them).
-Perhaps you should mention how Jigglypuff's shield-break kills her unless there is a ceiling above her.
Other than that, this is great. Thanks! =D
