I would say if you completed normal modes you have what it takes to kill the first boss, who is vastly undertuned. 502 minimum is easily what you will need to do the second boss onwards, and you'll need more and more as you advance through the instance. Ignore the people saying 480 is enough, they are doing it in 515+ gear and even if their 'lolalts' have done it in 495ish gear they aren't keeping in mind not everyone operates at the skill level of a 16/16 HC guild either.
Tl;DR: Mid 480s for Jin'Rokh, don't even bother unless everyone is at least 500 for anything else. Horridon requires more of your raid than H will before patch.
