C3PO was vital for both reasons mentioned above and I did not have a lot of trouble getting Jedi cards out when needed.
I built the deck on New Years Day and played it exactly twice before the tournament. I was looking for something that could possibly bring a lot of damage to bear quickly but cheaply.
I was Warriors of the Forest in every game. My one loss was to a Sith deck that beat me handily (even though I blew up 2 objectives and damaged a third). I never felt in that game.
When we I played it again I started with 2 Warriors of the Forest and a Rash Action in my hand (using it on Mara Jade) allowing me to quickly dispatch 2 of his objectives and I was able to get the third with a second Rash Action on Palpatine.
All in all the deck is really fun
