losing my mind here....

mdt and wds runing on server 2008 x64. One distribution point for builds and
one other deployment point for deploying wims.

I modified the deployment wizard to add a custom pane for collecting some
custom info. It is functional but I also modified wizard.css in the process
for the look and feel... it looks great when testing via the MDT wizard
editor (codeplex.com) but these settings are not applied when actually
booting from the winPE lti wim image...(after both 'update' and 'update
(files only)') I have tracked down via trial and error the fact that the
wizard.css file that is in the winPE lti boot wim is used and not the one
from the deployment point, although the DeployWiz_Definition_ENU.xml and the
DeployWiz_Initialization.vbs file from the deployment point *are* used,
*directly* from the deployment point.

so, wizard.hta, which uses deployWiz_Definition_ENU.xml and wizard.css (and
DeployWiz_Initialization.vbs, DeployWiz_Validation.vbs, WizUtility.vbs,
ZTIUtility.vbs) are all *in* the winPE lti boot image... but from my
experience the wizard.hta, deployWiz_Definition_ENU.xml, and
DeployWiz_Initialization.vbs from the deployment point are being
executed/used directly from the deployment point *but* the wizard.css from
the winpe image is used with them.

All this crazyness has lead me to a desperate need to get an answer to the
following (absolutely must know if customizing):
1. what really happens when you do and 'update' and an 'update (files only)?

1a. and most importantly for me right now: where are the various script and
config files taken from? (eg. there are files in the main distribution
piont, any other deployment points you create, and within the MDT program
files directory structure)

1b. which ones are used (or from where)? eg. I have verified wizard.hta and
its definition xml file and inititialization script are in the winPE lti wim
but the ones in the deployment piont are the ones actually used..??

1c. what are the conditions, if any, that affect whether or not certian
files are taken, and/or from where they are taken?

eg. I have my main distribution point (single server lab deployment point)
and another deployment point for deploying custom wims. All my
customizations were made to the files in my deployment point for custom wims
(not the lab one). When I update that deployment point (update files only
and/or update)none of the files you find in \deploy\scripts in the winPE lti
boot wim are updated (I list these files below), except bootstrap.ini if its
changed.

here is the list of files that is *in* my winPE image:
 Volume in drive X is Boot
 Volume Serial Number is D60A-0DC2

 Directory of X:\Deploy\Scripts
