Hello, I'm Kerlan, but I see you are already talking about me. Leif mentioned that there may be a opening in this game and I was just taking a look around. There's a lot of info here.
Well, here's what I see in your game.

So, you lost a ranged combat character but still have 3-4 melee types. You have a couple of arcane casters but not much battlefield control. You have a cleric which is the only one that can heal. You also have no rogue type PC. The Beguiler kind of fills in for that role. What role do you think you need? I'm rather partial to Wizards and brutes, but I have never played a Spellthief before.
What books are allowed? I see the books PHB 2, Complete Warrior, Complete Arcane, Complete Divine, Complete Adventurer, Heroes of Horror, Miniatures Handbook, and Tome of Magic. Are there any others like Spell Compendium or Magic Item Compendium, Races of books, all the Completes? Is it 6th level now, which would make prestige classes available?
