It's a party built for pounding.

More specifically, it's a party built for HP and combat by weapons.
I like to lean heavier on spellcaster classes, but that's a personal preference.
I agree with most of what Ravager said, with the exception of reducing Wis on the cleric - the higher the DC the better; I'd take the points away from Cha.
If you aren't averse to multiclassing, I could see some room for improvement. Some barb levels on those fighters (alignment permitting) adds more HP, rage, and movement if in medium armor or less. I would recommend that, as you have very high dex, and could thereby get away with lighter armors. Your AC might even improve.

You could have dropped Int a bit in favour of Wis. There really aren't any good skills for fighters (aside from Concentration, I guess), so the loss of skill points in favour of higher will saves isn't a problem.
I would have upped the Dex and Int on the Sorc slightly instead of that 18 Con; Dex makes it more useful as an archer when not casting spells, Int gives it more skill points for talking and identification skills.
The ranger needs no tweaks that I'm aware of.
The rogue could benefit from a few fighter levels, with four being ideal. It would get you weapon specialization, more feats for those good rogue options, a slightly better BAB... You could have dumped a few Wis points (hard to get through spell resistance and elven resistance to enchantments) in favour of Int for massive skill points.
Some of the same applies to the cleric; if the sorc is talking, Cha could be dropped. Some Con could be taken away for Str and Int.
