You can do the necessary changes in the ability Barracks - Train. Ability - Info+ -> Train Ghost -> Find Requirement, and click the red x to remove it.
Depends what you mean by attack. If you mean damage look for the damage effect for the unit's weapon and modify that. You can change weapon of the unit so it uses a completely different weapon and by changing the weapon effect you can add a whole lot more inbetween (look at broodlord or collossus as a good example). For changing the visuals of the weapon you must alter the actors for it.
forgive me for being a noob but how do you make a unit, say a ghost, to not need a ghost academy or a tech lab to be able to be made?

Thanks a lot!
So how would I change a units attack then?
