Comment and blog spam plus other stuff

I'm still trying to get uploads to work correctly. I just downloaded the
latest snapshot. I'm still getting the uploaded file landing in
wiki/uploadsharold instead of wiki/uploads/harold .

Next, there is, of course, a way to remove pages. Is there a way to remove
uploads?

Next, I'm having a real problem with blog and comment spam. I have the
system set to only allow logged in users edit pages. But, apparently users
that are not logged in can comment and blog. Is there a way in the config
file to disable unlogged users from creating content? Or should I just
delete these plugins?

THANKS!

Harold
