Hi,

Generally DS products are installed outside Runtime folder with (almost) the single exception of textures. Your structure looks sound. If I have a folder "My DS Library" for all the DS and Poser stuff, then I would place the DS version of Books into:

"My DS Library | Props | Kutter | Books"

and textures to

"My DS Library | Runtime | Textures | Kutter | Books"

As Richard said if you set up these things within DS using an active library, then the saved paths should be relative, i.e. your disk letters and names will be subsituted on client system automatically. I am Mac user, I won't survive if products would have hard references to disk letter, but I'm using hundreds of DS and Poser products without problem. :)
