It can be helpful to add in a few things, like priority, confusion (debatable), infatuation (debatable), defense, special defense, speed (we have HP,attack and special attack so why not). It's also possible to add status ailments as they're side-effects (like burn reducing attack, paralysis redusing speed and badly poisoned increasing damage every turn) but this is also debatable.
Adding tiny things like contact/non-contact moves, special, physical and status moves (meaning) can be useful as well, though the first is not at all necessary IMO.
OU, UU and Uber tiers are present, but RU, NU and PU (borderline and limbo too, but they are almost non-existant) are not there.
Adding the meaning of EVs and IVs is also a possibility, with a link about them more in detail below them.
Another thing: the meaning for HM is given, but TM is missing (for whatever reason are either of them supposed to be there :/).
Again, only suggestions, none of these really HAVE to be there at all.
