A few slight notes:
Joshua's best damage is pretty much MT. Teleportation and stuff avoid it, but if you're on screen and not in the invincible prone state, you take damage. Gives him some team use?
An additional setup for Neku, in case people weren't convinced he was broken:
LIVE!/Frantic/Mink + Stopper Spark + Straitjacket + 3 other pins
-This setup is constant Paralysis. LIVE! is storebought, but weaker than the other two; Frantic is better but a drop on Normal mode (5% off a decently tough optional boss, though, at 1 drop rate) and Mink is a Hard/Ultimate difficulty only drop (Given the nature of this game, that's not too bad; being a 0.30% drop at 1 drop rate is.) As a result, LIVE! is probably the most convenient. Stopper Spark is from a 100% rate of encounter Metal Slime-type monster (the pigs), and Straitjacket is storebought.
Also, some lists in the previous post were modified in light of new info.

Further notes:
All-around Upgrade IV gives +3 Atk/Def/+50 HP in addition to whatever other boosts the item has. Makes the My Phones even nicer for Neku, if you allow them.
