How do I continue my education in C# programming?

So I discovered a passion for programming- I really enjoy the programming process as a whole and started learning as a hobby. After a huge dilemma on which language to learn first, which was between C# and Python, I chose C# because I had read about Python being slower and it’s use limited to smaller apps. So I’ve been learning from this website: http://www.homeandlearn.co.uk/csharp/csharp.html and I think it is pretty fantastic.

Taking a look at the index, how do you recommend I continue my education? What (topics) should I look for in C# programming books to buy?
Taking advantage of the thread, did you think C# was a good choice? I plan to use my knowledge to create Windows programs and web applications.
