Help with imaging many new PCs and Laptops with different hardware

I'm really stuck here so can someone  give me help me with a step by step solultion?.  It's a big ask - probably not a difficult for an expert to do but for a beginner I just don't know how to start this process.  I have no images for multiple brands of hardware. I guess I have to install WXP on each type of hardware and add add the  apps then run sysprep and then make a ghost image of this.  But the sysprep part is a confusing and I certainly can't do an unattended file.....that is totally beyond me.

 I've tried for 2 days tomake a BartPe bootup but can't work out how to add the newtwork drivers and the plugins - I have an old Bart disk I used in 2003 but the latest drivers are not on it anymore.  So I downloaded the builder and followed the steps but don't understand exactly where to put the drivers and in what form?  Do youput the .cab files in the drivers folder or do you uncompress them and put them in their own folders?  The plug in for ghost - I have the ghost files but when I go to add it says it can't find them -  

I've read all the threads but there re so many points of view, I think I just need one expert to step me through this process.  Lots of techies do it in their workplace so I should be able to do it.  Unfortunately I'm all alone at work and don't have anyone to ask so I'm hoping someone here can step me through the process and make sure I'm on the right track.
