So after fooling around with different things for awhile I came up with this. My personal compilation of changes to make playing my warlock more enjoyable. NOTE:These are my own personal changes based on my preferences, if you don't like a few I won't redo em; take the files you don't like out of the mpq if you really hate some.

VOIDWALKER>>Red Mana Fiend
DREADSTEED>>Death Charger
IMP>>Fire Imp
TALISMAN OF EPHEMERAL POWER>>Red Moon Glow
DEMON ARMOUR>>Bone Armour
GRYPHON/HYPOGRYPH/WYVERN>>Ghost Gryphon
SENSE DEMONS>>Red Laughing Skull
WARLOCK SUMMONING>>Dark Ritual (summon)
WARLOCK PET/MOUNT SUMMONING>>Dark Ritual (pet summon)
SUCCUBUS>>Succubus (BLACK MODEL) I kept the succubus model itself but just changed the texture, mainly due to the feminism of the actions of the pet itself, just wanted to make her look "darker"..still, looks quite a bit better imo.
DOOMGUARD>>Outland Doomguard (black model) You will notice in the screenshot that the model is a bit buggy i.e. the wings are still red...this is changed in the actual MPQ to correspond to the rest of the texture. I didn't feel like getting 5 more people to sacrifice themselves for a screenshot
CURSE OF AGONY>>Green colored Curse of Frailty
CURSE OF SHADOW>>Mind Rot
FElLHUNTER>>Cool Outlands Creature ( I realize the majority may not like this particular change but like I said my preference, I was testing it out for a few days to see how I would like it as my fellhunter and it grew on me)
RED FIRE>>Green Fire NOTE! ~~ This includes Hellfire, Rain of Fire, Immolate, Soul Fire, and Searing Pain, all are green now and all of their active spells, not just the cast, are now Fel.
SEARING PAIN/CONFLAGRATE>>Exorcism (this is only the impact of the spells to the chest)
If you are like me and a lot of other WoW players 50% or more of the time you PvP you are in noggenfogger skeleton form. I decided to change the textures of that form to something a bit more cooler looking. White Nog Skellie>>Dark/Black Nog Skellie
Other changes that are not screenshotted:
Infernal>>Stone Keeper (this is untested, let me know if it works)
Felguard (warlock demenology pet)>>Black Textured Felguard
Shadowburn>>Shadow:Word Death
Thats about it; my goal of this model change for my warlock is simply to make the gameplay and spells and pets seem more "darker" and ritualistic..not exactly necromancer and not exactly elementalist, thus is why I did not have completely radical new creatures replacing the pets etc.
Enjoy!
