CrunchBang Linux

I am very sorry to ask a newbish question. forgive me.

I have been personalizing the crunchbang live cd in various ways for awhile now.  Now, I have decided to try working with the actual ubuntu minimal cd.  I understand (somewhat) how init and upstart work, but I am still confused about one thing. 

What starts openbox? 

I have looked in /etc/X11 for awhile and I was sure that it would have something to do with xinit, but that does not seem to be it.  However i did see a link to /etc/xdg/openbox within the X11 directory.  I have a feeling that that has something to do with it.  Can anyone explain this to me?

any help is very appreciated

I know what you are all thinking, "Wow... What a very descriptive title for your topic."  Sorry about that....

Let me just start off by saying that "I freaking love #!"

Anyway, I am building a custom "distro" based off of crunchbang.  My "distro" to #! will be like Linux Mint is to Ubuntu.  It is for my personal use only and it is basically just a customized install disk that does everything the way I like it. 

Anyway, I want to call it "Sunshine Linux".  I have made a GRUB theme, usplash, GDM, and stuff like that for it and they all say "Sunshine Linux" in some way, shape or form.  I have noticed a couple of other things that still say "Crunchbang, and I want to know how to change them.  Two such instances I have noticed:

1.  The screen that is displayed momentarily upon moving the mouse when the screen is locked.  I want to find the image file for that so I can customize it. 

2.  I don't quite know what to call this... I installed #! before I installed Ubuntu 9.10.  When I did a fresh install of Ubuntu 9.10, it installed GRUB2 as the bootloader for my pc.  It did a scan for OS's already on the computer and it identified that sda6 contained and OS called "Crunchbang 9.04" and it added and entry to my grub menu accordingly.  I was just wondering how to change the file that controls the "System Name"
