Mods and other stuff you might consider.

GAMEPLAY:

BLITZKREIG - More stuff to blow up with cooler effects.

Normady44 ETO - Realism Mod Focousing on bringing the most Realistically yet Blanaced experience to CoH.

Battle of the Buldge - Winter-mod based on the Ardennes Offensive AKA The Battle of the Buldge.

Eastern Front - Russians. RUSSIANS FFFFFFFFFFFFFFFS.

OMGmod - Similar to EaW but focused around Operation Market Garden AKA Operation Airshot .

Europe at War - CoH online without the faggot paid-heroes bullshit.

GRAPHICAL:

Historical Skin Mod - Duh. Historically Accurate.

GnirugH's HiDef Skins - Totally awsome. Also [Mostly] Historically Accurate.

More to be added as I recall them.

I recommend Eastern Front. It's a great CoH Mod.
