Any good C tutorials?

The best way to learn is try, but if you used visual basic, C isn't a problem, are too similar. I don't remember a good one, i'm in my work, but when arrive to my home, i see the name that the manual that I used and tell you.

I believe the title of the book is "Learn c in Thirty days" that is pretty extensive. Plus there is a neat pocket reference by O'REILLY publishing called "c syntax and fundamentals," with a cow on the cover. Borders should have both of them.

pretty much after the basics, its looking up documentation for using api's (you know, sockets, windows management, etc) and then just figuring out how they work

not really, i guess get as good as possible with pointer and memory management (remembering to free memory no longer needed)

the documentation thing is obviously only for api's you want/need to use
