Custom unattended install of Office 2003

[NOTS3W]

I hope someone can help me get my head around an unattended installation of Office 2003. There's a lot of information out there, but it's not coming together for me. I only want to install selected components (Excel, Word and Access) and I don't think command line switches will allow me to be that specific. Instead, I've used AutoIt which works well for the installation but I still need the service packs and hotfixes. I think I can slipstream the service packs then do an unattended install but that will install everything and I only want certain applications. Argh! Is there a way to update my installation files with the service packs then use AutoIt to perform the custom installation? Can I "install" the service packs and hotfixes via my AutoIt script after installing Office? Can I update the installation files then install the selected applications individually using command line switches for the serial number, etc. without using an AutoIt script? I don't see multiple setup files unless they're buried in cab files.

I've found many of the Options and Customization settings for Excel in the registry and can set things to be nearly perfect from the first time I run the program. I cannot find a reg setting that forces full menus (in Excel, it's: Tools ~ Customize ~ Options ~ Always show full menus). Does anyone know how to set that without going through the Excel menus?

Finally, how do you activate Excel's Add-In programs? This question has been asked at least a couple of times without response so I'm not holding my breath on this one. I can see the registry changes that occur as each Add-In is installed but that's only part of the integration. Something must also need to be installed in Excel for the Add-Ins to work. Are there executables that can be run from a command line to individually and fully install each Add-In? Currently, even after making all of the registry adjustments, none of the Add-Ins is active or checked on the Add-In list (Tools ~ Add-Ins) in Excel. In fact, on starting up, Excel displays a warning that the (which "the", it doesn't say) Add-In cannot be run and asks if I want to install "it" now.

If anyone can help me sort this out, I'd really appreciate it. I've gotten through the whole unattended installation process including a number of applications but I'm hitting a wall with these Office details.

Thanks.
