How often does Alexa crawl a particular site on average?
About every 2 months.

Is a snapshot taken every time a site changes or every time alexa crawls it?
Every time alexa crawls it.

How soon after a site change is it put into the archive?
Alexa donates their crawls to us 6 months later, and then it takes some time to update the Wayback Machine.
