You can use a disk cloning program to setup images of the hard drive once they are setup.
Good idea if you need to go back to bare metal again so you don't have to go though Windows and driver installation again.
Install all the programs and drivers, once it's working, create a bootable external hard drive with a cloning program, use that to make an image of the computer. If you even need to wipe it again, use that program to dump the image on the system in one step.
Keep backups of you files as well so you can copy them back after a re-image, My Documents, Favorites and Desktop are the main ones, also any email files you have from your email program (Outlook uses PST files, others will have different ones). If you use Firefox, export those favorites and save them as well.
