Debian has update-rc.d, I think it's the equivalent to Fedora's service command. Read the man page.
You can find documentation for most programs you install from under the directory /usr/share/doc .
There's also invoke-rc.d that does the same thing as "/etc/init.d/service_name start|stop|restart".
There are several Terminal User Interfaces (TUI's) for managing services in Debian, I like sysvconfig.
