True. But like Nute Gunray said "General, without Count Dooku, I have doubts about your ability to keep us safe." With Dooku gone they lost faith. They only stayed through fear of Greivous.
Grievous could easily convince planets to surrender out of fear, and Palpatine was calling the shots for what they both were supposed to do, not like Dooku was planning all of this.
I doubt that Greivous would be able to convince a planet to join the CIS through fear alone. Besides, GG was a wanted man in the Republic. If he showed his face in a Republic owned system he would e reported immediately. Dooku however can reason with the system, bribe the sytem etc. Then if something went wrong he can jusy use the force to influence them.
Dooku's importance was to create the army, start the war, and see that it moved on so it wouldn't be over in a week, and I guess so he could turn Anakin.
Dooku took care of the political side of the CIS, Greivous was the military side. Dooku still had to convince systems to join the CIS, he still had to make sure that all business ventures were running smoothly, he still had to make sure his acolytes were doing as told etc.
