No, actually I'm in IT and have had to create simple VB scripts occasionally.
In that case I think you are underestimating the endeavor you wish to embark upon. Not that you can't reach your destination, no problem at all, but the path is probably longer... you should probably be asking for books instead of URL's.
I would recommend the following:
1x Book on C# for beginners which also walks you through Visual Studio. Unfortunately I can't advise on this (I would ask Amazon).
1x
Book that takes you from understanding how to use C#, to understanding how to use it correctly
1x Book that deals specifically with development on WP8 and WRT
That first book should be focused primarily on the C# language specification and object oriented programming in general, NOT on the
.NET BCL. Very important!
If you really want to understand what you are doing with C#, you should probably also read
this.
By the time you are finished with the first two or three, books specific to WP8 and WRT will be available which currently aren't. That final book is the one that should focus on the library, and your choice may also depend on the type of app you plan to develop (games are very different from normal apps)
Good luck!
