Dorren's request isn't a very good place to level up legityly because of low synthesis levels of newbies added with the fact that the monsters don't give exp. It's also not very good for gold since the monsters do not drop gold. And finally, Dorren's request has been abused so much by cheaters on the game that all drops from it (mission reward chests) are worthless. If anything, I would suggest Crag Cow if any mission. It's relatively straight forward and you have an open field to run away if needed. Additionally the monsters Do drop gold and give exp. Plus the rewards (later on at least) are still valuable.
I saw you were looking at what weapons to get. I wouldn't recommend two-handed weapons unless you just like the play-style. Their functionality is limited. Gladius is a fairly good choice to dual wield. With the upgrade sequences found
here or
here you can make a pretty good choice as to how to upgrade them based on your dexterity (which provides balance to wield stronger weapons efficiently).
My suggestion, using dual gladius's as your primary weapons and some sort of weapon and a shield as back-up. Perhaps a mace or something. Anyway I'm no professional melee person or anything lol if anything I'm more of a ranger.
Oh also, you Might want to post in the questions/help section if you have a question like this ^.^ I'm no mod, but just a suggestion.
