Answer 1

The Microsoft Developer Network (MSDN) is a huge repository of developer information, e.g.:
https://msdn.microsoft.com/library/ (Microsoft API and Reference Catalog)

You'll probably also want to dig into https://technet.microsoft.com/
... click the links (library, wiki, blogs -- from Microsoft staff -- etc)

[More than you asked]
You may also consider joining the Microsoft Partner Network (free level gives you 5 seats of MS Visual Studio Online Basic). Their first paying tier (pay once, keep those licenses forever) -- gives you enough full-version software for a 10-person office, intended for learning and demos but otherwise not limited (so, Pro + Enterprise versions).

Answer 2

Youtube videos are quite good
