I would like to know what skills I should lvl up and what gear I need.
and what the best secondary class i should make him i was thinking warrior or priest, I'm trying to make him do as much damage as possible for farming purposes.

I think your best bet is Mage/priest or Mage/rogue

and you'll get items from quests mostly and there's set items that you should collect

you're looking Intellect and stamina stats

and for start you can put your TP "Talent point" to Flame, maybe someone could explain more.

what quest's and where do i go to get godly stuff and sick places to farm

godly stuff you get from AH and by doing them on your own.

I don't know how to get lvl 50 items because my highest lvl is 36 atm.

still looking for the skills u need to lvl up

Hi i would go with mage/priest cuz its a great choise, dd or healer every party need you^^
Fireball is a must >best dmg?! but 3sec cast time... you checked the rom forums on hp? there are for sure some guides too...
And about farming gear, start with MA later you should try CL or SoK but isnt that easy i wasnt there yet but a friend of my he just did CL today wholi instans with only 2 priests ^^
