I would give Panelo something other than Staves, because magic is pretty useless until you get the -aga spells, they take too long to cast, and then end up mucking up your cure spells because only one spell can be cast at a time. (if you have 3 people casting cure, and their Action Bar is full, one will have to cast their spell before the second person will, and the third has to wait until their done. A huge problem with spells, unfortunately. :\) Not only that, but spells below "agas" are pretty useless. Elemental weapons are better until then.
The rest are fine (so long as you get rid of Ashe's spear and change it to katana.
) I'd probably give Basch a spear or axe instead of a pole, but it's still doable.
I'm not sure if you've read up on this, but I thought it would help you on deciding what to use with which character. (taken from Commander_Greil's Final Fantasy XII Weapon FAQ on Gamefaqs.com)

Katanas:
Katanas have one best combo rate of any type of weapon, so they pretty
awesome. Damage is calculated by characters strength, magick power, attack
rating and opponents defense. Damage based on Magick is helpful because even
then your support characters can deal good damage.

too. Damage is calculated by character's strength, speed, sword rating and

power of gun and ammo. Note-It doesn't matter about enemy's defense. It
pierces right through.
