Lews Therin - Love the Wheel of Time reference

Congrats on your first post.
Anyway, after numerous restarts (in order to try out all the different kits) I would go with the following four PC's.
Fighter - Dwarven Berserker
+++ Axe
++ War Hammer
+ Sword & Shield
* IMHO better than barbarian since he has no armour restrictions, rage bonuses are cool
Thief - Halfling Swashbuckler
+ Short Sword
+ Short Bow
++ Dual Wield
* The BEST thief, unless you like to backstab...
Cleric - Any Race Priest of Lathander
+ Flail
+ Sling
+ Sword & Shield
* Which kit is kind of subjective, depends on party alignment I guess
Mage - Elven Sorceror or Human Conjurer
+ Dart or Sling
+ Quarterstaff
* If sorceror go with elf for higher dexterity and racial bonuses
Hope this helps,
