Hi everyone i just hit 50 yesterday as a warr and im wondering where to start now ?

Do i farm tokens in order to be able to do hard modes ? ( what dungeons )
what do i need as a tank to start doing ifrit and garuda ? ( dungeon and allagan tomestone gear ? )
Where do i start my legendary weapon ? ( And wich profession for warr)

I jsut want to know what to do exactly because at the moment i am unsure of what i need to do
