Damn. Read the book, search the web, make 'man' your friend. In reverse order:
Add 'Option "ZAxis Mapping" "4 5"' to /etc/X11/XF86Config
Chmod 600 /etc/rc.d/rc.fortune.sh or whatever it's called
Slack turns them all off except that that caused problems, so they left one open. Dunno why - runlevel 3's great.
Like a string of variable, aliases, and functions.
Dunno - don't use them.
Edit PS1 in ~/.bash_profile and/or ~/.bashrc
Edit /etc/fstab and add that partition like the others except say 'noauto,users'
Not sure about all that - lotsa questions. But try some of that out, do some of that research, and read people who correct me.
