Don't know if this is the problem, but I was having issues with Eclipse Helios where when Eclipse was abnormally terminated, it took forever to restart. The way to get around this was to delete all the ".snap" files from the .metatdata.
Deleting the .metadata entirely is likely to lose more important project information, however. If you do that, you'll effectively have created a new workspace and you'll probably have to import the project files into it.
Customer surveys are for companies who didn't pay proper attention to begin with.
Yes, the .metadata directory contains all of the information that Eclipse maintains about the workspace. If you delete it, the workspace is gone, as far as Eclipse is concerned. You can the reopen the workspace directory in Eclipse and then import existing projects.
