There are no such bugs in either 3.0.1 or 3.0.2. Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Ten theme to rule out any theme-specific problems?
– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress?
– increasing the memory available to PHP?

I have several themes with the same version of WP and all the possibilities you gave tried and ruled out. So there are bugs and also mention by other users. PHP is up to date so is the memory of it.
What version of PHP are you using?
I have to agree with esmi here, those bugs do not exist on a plain vanilla version of WordPress 3.x so the issue is most likely to be your server/configuration.
This is de information
PHP Version 5.2.14
System Linux tb009.terrabyte.nl 2.6.18-194.17.1.el5 #1 SMP Wed Sep
[Mod note – edited. Please use a pastebin if you want to post the entire configure line.]
If the wysiwyg is not showing in the post editor it almost always a plugin or theme conflict, or a server issue.
Your issues are not bug – we can’t reproduce them on a clean install.
