Mahesh Chand has an intro to GDI+ article at vbdotnetheaven.  He also has an article describing GDI+ brushes.  Finally, there is also has an article on Pens and Fonts. 

Budi Kurianwan has nice article in C# covering the basics.

Bob Powell has an excellent intro article, and he also maintains the GDI+ FAQ.

Remember that Pens are used to draw lines and shapes, Brushes are used to fill surfaces, Fonts are used to render text, and Colors are... colors.

I suspect it would be good to know the different types of Brushes available: SolidBrush, TextureBrush, HatchBrush, LinearGradientBrush, and PathGradientBrush.

Image class is abtract, Bitmap and Metafile are the actual implementation classes.

The graphics class can draw the following types of shapes/lines: Arc, Bezier splines, Closed Cardinal Spline (ClosedCurve), Curve, Ellipse, Line, Path, Pie slice, Polygon (regular and irregular),  Rectangle.  It can fill a Closed Cardinal Spline, Ellipse, Path, Pie slice, Polygon, or Rectangle.
