Welcome to the group sir!
each pack has a changelog and a DEVICE list available from the overview page.
since this is a laptop then you may want some of the packs from the 3rd party DriverPack section / forum too. (modem, ect...)
we take a different approach than waht you are expecting. we add all the packs then 99% of all existing drivers are available.
So it will work on ANY machine. if you find a driver that is not included just grab the HWID tool that is in all of our signatures and post that with as a [REQ]uest and we will add it (that is how we get to, and maintain, that 99%)
best bet is to get all the main packs and just the 3rd party DriverPack that you think you will need then make a test UXP disk and test it
verify your backup or ability to restore vista just in case. Idealy you would have a second HDD for this, but i understand if not.
Laptops are often dificult - if the OEM doesnt offer xp drivers - sometimes we can still help but often it comes down to you being able to tell us what works or does not work.
Thanks and have a great day
