The White Council assaults Dol Guldur?

[Legate of Amon Lanc]

The original idea of this topic came to me on this thread.
As we all know, in the year 2941 T.A. the White Council drove out the evil power from Mirkwood. This topic greatly interests me, so I thought that I'd try to put together what actually happened there at that time. If anyone feels interested, I'd like to see your opinions, or evidencies you bring to let more light in this story.

The questions to which I hope to find answers here are:

1. Did the Wise really, personally, come to Dol Guldur?
2. Who was actually in the White Council?
3. Were they all there in Dol Guldur, or someone stayed home?
4. Were they all alone in the forest, or did they bring an armed force with them?
5. If they did, whom did they bring? An Elvish commando from Lórien, or something else?
6. Was there actually any battle? Did Sauron flee before the attack, or during it?
7. How the battle looked like? Galadriel sings a song and half the wall of Dol Guldur's fortress crumbles down? Saruman shouts exorcisms and the spirit of Sauron flees? Or Glamdring swings above the heads of Orcs?

To make this clear and to keep up with the topic, I used the numbers to mark the questions, so if you are trying to answer any of the questions, please put the number in your post to show what you are replying to. Try also to support your meaning by quotes from the books, or just some evidence from the books (e.g. to answer #5: I surely know they didn't bring Beorn with them, since he was in the Battle of Five Armies by then, and even he didn't have any contact with anyone except Radagast before then), or at least tell that what you make is pure speculation or just a fan imagination (concerns mainly question #7, which is really there mainly for releasing our fantasy. Nevertheless, even that could be supported by some evidence - e.g. Gandalf can kill Goblins with lightings, as we know).

Hope this topic would be fun at least for someone

EDIT: Since I already started this topic with a nice lining-up of the answers, I'll keep here also a list of the current progress of research (wow, that sounds). This is mainly for that if anyone wanted just some answers, he wouldn't have to read through million posts to come to them. The list would be, of course, updated.

List of current progress in answering the questions:

1. No suggestions yet.
2. Solved: Saruman, Gandalf, Galadriel, Elrond, Círdan. Possibilities not yet closed: Glorfindel, less likely Erestor, Celeborn, Galdor.
3. No suggestions yet.
4. A suggestion about that they had a "fire support".
5. A suggestion that hey had elves with them to shoot escaping Orcs.
6. No suggestions yet.
7. Proven information that "the devices of Saruman" played main part in the battle. But what exactly they were is not sure.
