Question : Debugging an ASP.NET web application?

I want to learn more about how to debug a web application:

1) How do you turn on page-level tracing in C# for an ASP.NET web form?
2) Can you debug into the JavaScript?  If not, wasn't there a version of Visual Studio which allows that?
3) What other handy trick are there for debugging ASP.NET web pages?

Thanks,

Turns out, load balancing with Form Authentication has issues. I'll just use Windows Auth with basic for now...
