1. Try reproducing the bugs on the test servers linked off of http://dotlrn.collaboraid.net/test/
2. If they're there, file a bug report at https://openacs.org/bugs/ (search for existing bug reports using your browser's search feature first)
I've fixed the customize portal layout bug. Not sure about the others.

I checked the test server.
The portal layout bug has gone while the others are yet there and I filed two bug report under Dotlrn.
