Aside from the Stamp and Stencil palettes in the bottom tray, there are a few other supportive utilities to modify your sculpture and environment. The Falloff tray has a list of presets where the curve represents the brush effectiveness as it diminishes from the center towards the outer edge. Material Presets have to do with how the surface renders and interacts with the light. Lights can also changed by picking a new lighting configuration from the Lighting Preset. Then the last tab in that section is the Camera Bookmark where you can save the current position of your camera. Choosing anyone of these presets will update your selected mesh immediately in your viewport.
A very important and helpful option that you have is the ability to mirror your strokes over a given axis. When sculpting something that's symmetrical in nature, like a human or a prop like chestplate armor, it would be very difficult to try and match your strokes by eye. And alternately, it would be too many steps to do half of the model, duplicate, reverse, and match its position opposite of the original. Never mind if you've made a mistake and have to start the process over again. With mirroring you can sculpt as if you are working on one half of the sculpture, but get immediate feedback as to how the mesh looks as a whole. And if you need asymmetry, it's no problem to turn it off when it's necessary.
Before you begin painting, a new paint dialog panel lets you set up the channel you will be applying the paint and texture to.
Another helpful sculpting option is the ability to sculpt based on the displacement map from another model. This is great if you need a means of transferring characteristics of one high-definition model to a base mesh. That way you don't have to start from scratch every time, especially if you know the general topography has similar characteristics.
Besides referencing displacement maps, you can also import in your own image maps as textures that can be used as a stamp or a stencil. Near the 3D View tab is the Image Browser, which can be routed to a directory comprising of your images that can be used as textures. Selected images have their information displayed above it as well as giving you the ability to rotate and resize to fit. And when the image is ready to go, it can be set as a stamp, stencil, or image plane. So if you have some good ideas for textures or patterns, Mudbox gives you access to your own ideas without being confined to just their offerings.
