Bzip2 support is not part of a minimal install. It is a tiny program, but you do have to install it. You can find the rpm for that at http://rpmfind.net//linux/RPM/fedora...2-16.i386.html
I don't know samba, but the values you are playing with are for the website. You say you are doing webdevelopment, but I don't see what the association is between samba and the website. Why not use ftp? You should not have faulty permissions on the website, or when you move the sites to the "real" server things may break over permissions. Apache2 usually runs as www-data, so that should be the owner of the /var/www/html directory.
