Here's what I've come up with so far.  This is a rough draft for Saturday and I'd like some input based on the missions and what I've got.

Lords:

Grey Seer on Bell
Potion of Toughness (I find he gets chopped up on the first round of combat, this should help with that)

Heroes:

Engineer with Doomrocket

Plague Priest on Furnace
Level 2
Plague Censer
Ironcurse Icon
Shadow Magnet Trinket

Chieftain- BSB
Great Weapon
Talisman of Protection (the 4++ one)

Core:

50 Clanrats
Shields
Full Command
Poison Wind Mortar

30 Stormvermin
Full Command
Shields
Storm Banner
Warpfire Thrower

51 Skavenslaves
Musician

6 Giant Rats, 1 Packmaster

Special:

40 Plague Monks
Full Command

3x Jezzails, Sharpshooter

5 Gutter Runners
Slings and Poison

Rare:

Hellpit Abomination with Warpstone Spikes

Hellpit Abomination with Warpstone Spikes

Doomwheel

Plagueclaw Catapult


Total:  3000 Points

This list isn't ideal, but it's based on what I have.  I am flexible on some of the things I can bring.  Here's what I have in addition to what's listed that I can use to tailor my force.

Engineer/Grey Seer (on foot)
Warlord/Chieftain
Plague Priest
Extra clanrats/slaves (can adjust any unit's numbers, possibly create a new one)
10 Stormvermin
Warp Lightning Cannon
At least 8 Rat Ogres
Bunch more Giant Rats
Warpfire Thrower/Poisoned Wind Mortar

I'm worried that my clanrat and plague priest units may be too large.  I may shrink the Clanrats down to 40 and the Plague Monks down to 35.

Hopefully I'll be able to focus this list and have a solid one by Saturday.
