Having got myself a card reader my pics are now reaching my PC (OS is Win98 so Nikon View 5 wouldn't load). I've added a CD writer so I don't run out of hard disc space.
My next query is if I'm shooting in Fine JPEG mode, which seems to be the best compromise size/quality, what happens to the shooting data (exposure, WB settings, date, time etc.) which you can access on camera? Is this lost for good during the transfer or can it be attached for good?

The shooting data is stored in the header of the JPEG file - it's referred to as 'EXIF' data. If you edit the file with an application that isn't 'aware' of this data then it won't be included when you re-save the file.
If you copy your shots to your computer via a card reader and write the .JPG files to CD without modifying them in any way then the shooting data will remain intact.
EXIF Reader is a freeware application that can retrieve the data from your files, although it may not be able to display all the D100 parameters yet.

All digital cameras today implement a common image format known as EXIF. EXIF is a combination of the venerable JPEG image format and non-image data extensions (stored within the JPEG data stream as COMment blocks). Specifically, EXIF picture information (also known as metadata) includes things like original image size, camera used, date the picture was taken, aperature setting, and exposure time. Unfortunately, not all of the EXIF data fields are required (there are a handful that are mandatory but implementing the rest are up to the vendor).
Anyway, Nikon was kind enough to include much of the shooting information directly inside the JPEG files. You'll need an image viewer that is capable of reading JPEG comments to extract this "hidden" information. My program of choice is ACDSee... just pull up the properties for the image and you'll see the metadata.
I see that there's a lot of extra information in the "maker note" and "user comment" fields, which suggests to me that Nikon is probably including more information, albeit in a non-standard format that programs like NikonView probably understands.
Included is a screen shot of some of the fields included in a recent D100 sample shot (by Mark Porter, over at pbase.com). Here is the original image:
