I would highly recommend this book: http://www.amazon.com/5-0-Nutshell-The-Definitive-Reference/... . The authors really know their C#. I have the pocket edition of this book and have looked at the full version, and it looks like a much more in-depth version that would be useful for someone just starting out.
I have no experience with C# on a mac, but I know it is possible. See: http://www.mono-project.com/docs/about-mono/supported-platfo.... You'd probably have pretty good support for anything on the CLI, but might run in to issues if/when you make the jum pto GUIs. Good luck!
