2500 pt Orc and Goblin list

Need some input on my new list I put together. I have been trying to find a list that is fun to play with and will win me some battles. I have two main blocks of infantry, Savage Orcs Big Unz and Orcs, that will house my Black Orc General and BSB; as well as my Great Shaman with shrunken head for the ward save boost. I tried to maximize my magic with my Lvl 4 for Big waagh and 2 lvl 2's for lil wagghh. My main spell I need and will be using the most will be the hand of Gork to get my units across the board as quickly as possible. Alot of my units rely on getting into combat quickyl In my mind the units to use the Hand of Gork on in order are the pump wagons, Mangler Squigs and then N.G. blocks for fanatics. Any suggestions on were I should house my two level 2 N.G. Shamans? My N.G. units are nothing but fanatic delivery systems and have no survivability. Should I still put them in those units or what? My chariots are in one unit and have been beefed up to maximize killyness. I will try to move the chariots, Manglers and pump wagon up together so the enemy will have to choose what they want to focus on. I have had zero luck getting my pump wagons in the charge so instead of putting in a couple plain pump wagons; I put in one pimped out one to hopefully get the charge on the opponent.

Questions?-
How would this list rate for winning?
Do you see any major flaws with the list?
Where do you house the 2 N.G. Shamans?
What unit(s) would you put the General and BSB in?
Would you do one Level 4 Orc great shaman or two level 2 orc shamans?
is there to many fanatic delivery systems? Would you keep thee blocks with 2 fanatics in them or two blocks with 3 fanatics in them?
Opinions on giving the savage orcs 2xhand weapons and Orc boyz spears and shieldS?

Thanks for all the critique and help!
