The weapon racks haven't been spawned, you'll need to do that.
The way quest objectives are handled was recently changed, the required NPC's and GO's for a quest is now stored in the quest_objective table. In saying that you shouldn't need to change it as all quest objectives have been already added to the database.
The RewardOrRequiredMoney column no longer exists and has been replaced with RewardMoney as required money for a quest is now an objective.
