please see: man init

Some of the differences between run level 3 and run level 5 would be
what is started/stopped in /etc/rc.d/rc3.d and /etc/rc.d/rc5.d and what
is started in /etc/inittab.

There could be other differences if any scripts executed by the init
task check the RUNLEVEL variable.

I would suggest doing 
ls /etc/rc.d/rc3.d > /root/rc3.d.log
ls /etc/rc5.d/rc5.d > /root/rc5.d.log
diff /root/rc3.d.log /root/rc5.d.log
to see what scripts are run in one level which are not in the other.
If something is in /etc/rc.d/rc5.d that you want in rc3.d, either
manually create a symbolic link in /etc/rc3.d similar to what is found
in /etc/rc5.d, or better and hopefully, if the script is recognized by
chkkconfig, use chkconfig to have chkconfig create/remove the symbolic
link.  Please see: man chkconfig

I would suggest looking at /etc/inittab to see what is different
between run level 3 and run level 5.

Please see: man inittab

I would not suggest editing /etc/inittab, commenting out the 
# Run xdm in runlevel 5
x:5:once:/etc/X11/prefdm -nodaemon
It would lead to confusion later should you ever wish to automatically
start X, because, like me, you will forget you made this change.  ;)

Long ago, I booted up in run level 3, logged into a command line, and
used the command, startx, to start X.  I haven't done that since I moved
to FC5, and now FC6.  I assume that would still work.  
Please see: man startx
