Here you go Hertsman, I think this will give you a feel for the product.
Just cleaning the car for my wife so took a pre extraction picture so you can see the setup.
The roll folds completely flat and doesn't get in the way. I took a shot of the fixing points - four press studs. It's secure and never comes off. It has to deal with a 13KG Welsh Terrier enthusiastically trying to get out for his walk on a regular basis and despite paws and claws, you can see there are no signs of wear or damage. Even if it did get damaged, it's about £15 to replace.
The grey doesn't match Pure Grey but it does brighten up the boot a bit. I've got a black one in the CSS and it's just as nice but being dark, shows every spec where the grey is a bit more forgiving. All personal choice of course.
Spoke to my detailer and they have the same cutting pattern as VW so the PPF option can't really be bettered and on reflection, now that I have this, think it offers better protection but also protection I didn't count on needing. My wife being shorter than me, needs to lean further in to get to the back of the boot so it saves her clothes getting filthy. You can position that to your wife before mentioning all the impractical accessories that you added! 
I don't think there's much else I'd do. I got key protectors on ebay, just to stop the key getting dinged. I have a GTI keyring in silicone which I rather like too.
Make sure the dealer sponsors this sort of additional stuff although the Weathertech not being official won't be an option of course.
Seems read this on move and then forgot to reply:
Weathertech looks real quality there and the grey does work really well and was convinced, but was telling a colleague what planned to do and he convinced me to hold my horses as he has in his garage a 'Cool-Liner' thats in wrapping and completely unused - He bought it for his GTI PP but the garage surprisingly gave him an OEM version and some other bits and bobs for a delayed delivery.
He back in the office next week so he bringing it in then for me: The weathertech is £120 with postage and as much as will pay the ££ for right item he says the cool-liner is truly decent, as good as any OEM, and I should see it first - will cost me a breakfast so thats what doing.
In terms of bumper protection, my loading is more infrequent and general so have bought a strip of 3M ventureshield for that top edge and will just see how it lies and how intrusive it is.
I have bought the OEM silicone GTI key protectors also and they look great
Think thats me done in terms of accessory, given coming from the black on black R environment, its like a smorgasbord of red accents and trimmings in comparison, so need to stay on the side of tasteful
Thanks for taking the time to post the images, much appreciated,
