replies to your quetions!

1.) the first characters do not do more damage than the others depending on their jobs, job levels and the character's level, also if you have a character on the 'rear' position it will do less damage but more defense regardless of it's position in the party!

2.) I have the same layout as you! these are the same jobs as in my party! the monk takes a while to level to its full potential but once you have reached a certain level it pays off! also my tip for using a monk is don't equip it with weapons! they attack better bare handed with no weapons at all! though keep your armour!
