So, now you have a decision to make:
1. Just get an opaque (black, I assume) bra to cover up the stone dings like a lot of us do or;
2. Have the nose re-painted and then put an opaque bra on it or;
3. Have the nose re-painted and put a clear film on it. If you choose Door Number 3, then wait a year between the re-paint and clear film application OR have the paint shop bake it under the lights for whatever duration they recommend to cure the paint. And do the primer/paint combo Alan recommends - some primers bond much better to the color coat than others.
The quoted $750 for a clear film is pretty much the going rate, nation wide, but ask the installer if he/she is using a 'pre-cut to a template' set of clear films or if he/she is winging it with a bulk sheet. Both methods work and both look good, but IMO the template version can fit better, depending on the talent/experience of the installer - Those that can make a bulk sheet fit all of the compound curves of a Speedster nose are very talented, indeed.... There's nothing flat out there. A template for an original 356 Speedster will fit our cars, too. How that works is the installer has access to a database of cutting instructions for a computer-controlled cutting machine. He/she downloads the template he wants and the machine cuts out a bunch of pieces that get applied where the instructions show to place them. That way, he/she is not cutting off puckers or wrinkles free-hand (which can be done artfully and look very good if done right).
I've had a clear film on my car since 2004 (done free-hand) and while it has suffered a bunch of "hits", only one punctured the film and that was fixed with a tiny dab of clear nail polish (to keep dirty water from getting behind the film). It still looks like this (photo taken last year) and that puncture is centered on the horn grill, halfway between headlight and grill. The rest of the specs are bugs yet to be washed off. It is starting to slowly darken, but the light has to be just right to see the difference. Removal, down the road, is done with a low-temp heat gun and a solution of 50/50 water and alcohol, if needed.
