Are there are resources out there which act like the layout grids and resources, but focus on fonts and stylings?

The YUI grid tool, 960 grids and others all give good resources for layout, and I've seen a number of tools that help with color selections, providing a palette of colors that 'work' together. I've not seen anything that provides a similar 'pre-fab' approach to fonts and font stylings.

There's probably something out there, I just can't find it. Any pointers?
