Answer 1

Station wagon in today's realities is a loose concept. If we take the maximum, then this is:
1) Working with data sources (SQL, XML, JSON, etc.)
2) Server logic (a bunch of languages ​​\u200b\u200band platforms to taste)
3) Client logic (Javascript and its frameworks)
4) Layout on HTML5 , CSS3
Further more exotic
5) Web services, RestfulAPI and other technologies for communicating with third-party services It would be nice to season all this with an understanding of the architecture of loaded applications, knowledge of current encryption methods. Well, I think the icing on the cake of all this would be - an understanding of building graphical interfaces.
6) Various authorization methods (domain or through SSL certificates for internal applications and secure storage of personal data and passwords for public applications)
