How do you prepare this stuff for use as a soil improver, or do you just
dig it straight into the soil?

I believe that is the traditional method - there may be better ones.

Also, is coastal sand any use for mixing my own compost, or is it too
alkaline? Is there any simple and cheap way to treat beach sand to make
it usable, or is it ok untreated?

Wash it. It will have too much salt for many plants, but salt is
readily soluble.
