Fiddler
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language. Fiddler is freeware and can debug traffic from virtually any application, including Internet Explorer, Mozilla Firefox, Opera, and thousands more.
Here is an excellent article on using Fiddler from a friend of mine, Steve Orr.
If Fiddler does not work for you, HTTP Debugger Pro is another great option.

Process Explorer
Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.
The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts. Information displayed in the bottom window depends on the mode.
The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

Microsoft Visual Studio 2008 Express
C# for free, yes free!  Doesn't have all the templates and features of standard, professional or enterprise versions, but you'd be surprised how much you can get done with this free edition.  Great for tinkering around at home.  This includes MSSQL Server 2008 Express also (just get the Management Studio Express in the link above to access the database via GUI tools).

Microsoft Visual Web Developer 2008 Express
Oh my god!  This free replacement kicks @$$ over FrontPage.  Full HTML editor with complete WYSIWYG designer.  CSS support.  Java and AJAX enabled.  Complete toolbox of widgets.  I could go on and on.  Can't believe it is free.  Works great for simple sites.  Unlike FrontPage, HTML output is not bloated (esp. if you use cascading style sheets).  This is the engine behind Visual Studio's ASP.NET form designer.
