Regarding the clubs, I am not a 100% sure. I believe I recall an official changing of the rules, that meant that orcs were allowed to buy and use clubs from the start.
However - it is NOT allowed to use any armor not listed along the starting equipment (Ilthmar and Gromril armor are both regarded as heavy armor).
So your orcs may "only" wear light armor. Goblins are only allowed to use shields.
