Think i would go for a deamon army, with CSM allies, as you seem to have more deadom stuff.
If you do, 2 cheap boxes of direwolves or chaos hounds are a good investment as flesthounds.
with those, and the rest of your deamons, you have a good base.
Not optimal, competivly, but fine.
for your warlord, the deamon price, nurgle, or the GOU are both very good.
Your problem in the CSM department, is that a chaos lord or sorcerer on foot is.... disapointing... to say the least. they never get where you want them.
you could go khorne lord with berserkers in land raider. thats expensive, but dangerous.
