Have any of the attacks been updated with STAB now that it's known?
Not really. The "issue" with the stab damage (specially in DPS values) is it will probably have to be added individually to each Pokémon page.
Not sure if anyone has any good idea for this.
Should there also be a mention on one of the pages about the different multipliers to different attacks (Such as STAB, super effective, etc.)?
