You might be able to get specific info through Democrats Abroad. Michael Steltzer is the head of the Berlin division, and though they are not in charge of the event, they are trying to get a large turnout. Here is the contact page.

"For security reasons, do not bring bags. Please limit personal belongings. No signs or banners permitted."
http://my.barackobama.com/page/content/berlin_event/The site for the speech has changed:
"Democratic presidential candidate Barack Obama will deliver a long-planned speech later this week in Berlin at the Victory Column in the city's huge Tiergarten Park, not the Brandenburg Gate, which had been under consideration."

http://www.bloomberg.com/apps/news?pid=20601039&refer=columnist_shlaes&sid=awZ8YTBD0KDU Great quote from article about preps for the visit:
"Getting here a few days early, I got a sneak peek at how the site will be transformed. These gates will set up a perimeter, and police are already directing traffic away from portions of the site. I asked one officer why -- as some German commuters grumbled about the extra traffic -- they weren't allowing cars around the column and he told me,
"because the president from America is coming." Language barrier, probably, but he was the second person I spoke to today who made the mistake. http://www.washtimes.com/weblogs/bellantoni/2008/Jul/22/1300-journos-want-to-witness-victory-column-speech/Some more info about security:
"Starting at 4 p.m., Obama fans will be allowed to start converging around the Grosse Stern and the Strasse des 17. Juni, the wide boulevard running east-west between the traffic circle and the Brandenburg Gate. But they won't be allowed to bring much more than the shirts on their backs. "Please limit your possessions to personnel effects," reads the poster, which also warns that people carrying bags will be the first to be denied access for security reasons. Security measures in the area surrounding the stage will be tight. The German Federal Police Office has classified the Obama event as a class-two danger level ("a terrorist attack cannot be ruled out"), and more than 700 officers are planned for the event.
Placards and banners have been banned around the Siegessäule -- Obama's team clearly doesn't want to leave anything to chance. They don't want to see anti-McCain slogans or anti-American statements that wouldn't be well-received back home." (This is interesting, because the anti-Obama folks are spreading the word that the campaign doesn't allow posters, etc. because they don't want Obama protest messages. When I volunteered in Detroit, the staff made it very clear that the reason was what is stated in this article...to prevent Anti-lying weasel, etc. messages. They said any Obama protesters should be tolerated as long as they didn't disrupt the event.)
