Hi,I was wondering if anyone has a recommendation for a contractor who can do installation of an acrylic bath/shower in San Diego (near downtown).

The finish product will last a very long time, be water tight, and look far better than a fiberglass or acrylic surround.

You could also use acrylic caulk, sand then kiltz.

With advances made in acrylic/hybrid paint technology, there are some really fantastic products on the market with water cleanup. 

I'm considering installing sound proof acrylic window inserts (secondary glazing) that will reduce the amount of noise.

Most likely I will go in and fill the holes, peal off de-laminated areas and fill them too, with an acrylic base wood filler.

Dropping in a form fitting acrylic shell sounds like it would fit the bill nicely.Any advice?

I would get something nice in acrylic.

I might just take this opportunity to get the shower fitted with a new acrylic shower and bite it as a maintenance cost.
