Check out this if you use SysVinit:

This tends to vary just a bit for each distribution.

http://www.linuxdoc.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html#toc6
is a pretty good discussion

If you want a lighter, slackware-specific (but mostly general) discussion
http://www.slackware.org/config/init.php
won't steer you wrong.

1. RTFM

http://www.linuxdoc.org/guides.html at least the System Administrators
guide.

http://www.linuxnewbie.org/nhf/intel/osbooting/ The SysV init has info
on what you're looking for.

http://www.mandrakeuser.org/docs/admin/aservice.html Has Mandrake info.

http://netlab.cse.ucsc.edu/redhat/doc/RH-DOCS/rhl-rg-en-7.2/index.html
(Mirror for RH 7.2) Look at the Boot process, Init and shutdown. 


2. Now for the answer:

/etc/inittab tells the system (actually, init) what to load and run on
different runlevels.

/etc/rc.d/init.d (on Mandrake/RH) has all the scripts.

/etc/rc.d/rcX.d has links to the scripts that should be _S_tarted or
_K_illed. (stoped)

To manage these scripts there are a few tools (look at the links above)
for the command line and some specific for the distro. Others prefer to
do it by hand and just 'rm' and 'ln' to their hearts content.

A few other files are general /etc/rc.d/rc.local and such. I don't think
RH and Mandrake fully comply to the LSB so they set up links everywhere
to look standard.

To speed your startup, dissable all those services you don't need. You
can try booting in single user mode to see how long that takes. Anyway,
you shouldn't be rebooting that often. :-)
