I killed the vampire tutamun in Pierce's cellar but only the quest for the murders in Verdistis got solved. He didn't mention anything about george although while talking to him there was an option asking him about george but i prefered to ask him if he is involved to the murders. Do i have to report to Mardaneus? I've already sent him to the council of 7.

You should have opened the option about George in the dialog with Tutamum.
But anyway don't have any regret because you have already sent Mardaneus to the council and it is too late for solving George's quest.

in the sewers there are 2 entrances to the castle. one for the prisons and one for the treasure room. First i Prefered to enter the treasure room where I was trapped and i saved Zandalor. He gave me the quest to go to the treasure room to find the sword of lies. it wasn't there so i returned back to him and we teleported out. when I try to enter again the treasure room from the sewers the entrance is blocked by the magic force shield, the trap that the black ring guys set up. Also in the prisons I can see a guy imprisoned an I think it's Dorian, the guys who was butchering the cows. How can I save him????

Yes it is Dorian but you can't save him now.
Dorian is not a bad guy, you should have let him free when you solved the quest about the cows.

Also when i Killed Cybu with commander's Ralph help. He told me that he will inform the stormfist castle and i'll get an invitation form Janus. Well nothing happened. I went back to Ralph's Headquarters but still nothing.

Go back to the place where you kill Cybu, you should find a letter on the ground.
