You flatter me, especially since I just foobared over in the SoA forum.
Your party will not encounter much difficulty, save the boss of the level(naturally, but with your party make-up, there is a surefire tactic to defeat said boss. Not spoiling you though
).
Besides the boss, there are no other serious problems, so long as you are careful and not too brash. Level 2 is more about brains than brawn.
I highly do not recommend level 3 until you start getting High Level Abilities as there are boss parties that will boggle your mind.
