#1 - The Tri-mil exhaust is pretty popular for a stock sized engine:

#5 - Every one that I have seen says Porsche on the dash.
#6 - The tan would contrast nicely with the cream paint and maroon but if you change to tan carpets then you will have four colors going on. The cream, maroon, tan, and the black. Might be too many colors.
#7 - Easy enough to have made or you can order a set from Kirk at Vintage Speedsters. www.vintagespeedsters.com
#8 - A lot of the guys on this website with CMC/FiberFabs have done that so there is a lot of information available.
#9 - Easy enough for an upholstery shop to do or do it yourself since there isn't any fancy stitching or door pockets. The "board" material under the vinyl is avaialable at a variety of places. Take the old panel off, trace the pattern for the new board and cover with new material. If you want stitching or door pockets see an upholstery shop.
#10 - Do you have the tonneau cover and it needs snaps or do you need a tonneau cover? A canvas shop could easily make you a tonneau cover.
#11 - I have yet to drive mine with the top up so I don't use the side curtains.
#12 - Easy enough to do with paint, insulating material, wire covers, and new tin pieces you can buy in kit form from one of the online guys:

If you order a new shroud make sure it matches what you already have. It'll either be an upright shroud or a doghouse shroud. JBugs website explains the difference.
#13/14 - I'd leave the engine lid w/o the louvers and I wouldn't flare the fenders. In my opinion the cost to do that now would be more than it's worth.
#15 - The cost of the car is directly proportional to the amount of pleasure you are getting out of it. There are a variety of opinions about value. I paid $23K for mine and it was built by Vintage Speedsters in 2001 and I think I got a very good deal. It has a 1915 cc motor, great paint, and a flawless interior. Some guys have paid more and some have paid less. I would imagine $15K give or take.
