Normalize file names is fine before you add substyles...just be on the lookout for a couple of images that get named too long sometimes...the images will seem to disappear.
If it happens just rename the image and they will pop back in.(usually logoff related stuff,they show in analyze as flagged longer than 60 characters)
This is your baby now...hehehehe,do what you like.
(my only suggestion is to use the layer styles in the psd for consistancy,not just he texture...but like I said...its your headache,er,project now)
