With this Tab there is an option to retain the color or to convert to Grayscale.
Split Toning is a process where an image is toned with two different colors. One color to affect the darker tones and the other color to affect th lighter tones.

The Tone Curve can give a large amount of tonal variation in the image to obtain a satisfying image.
The Parametric Curve Tab has four sliders below it to adjust the shape of the curve.

The Adobe Camera Raw Histogram is generally an indication of correct exposure. The left side of the Histogram should indicate pure black and the right side should indicate pure white. A perfect Histogram will not have any of the Histogram content extending beyond the right or left edges. Some contact with the edges is sometime unavoidable, however if it is too much some of the content of the image will be lost.

The Adjustment Brush Tool is used to paint over an area you wish to change in the image. The brush has options for Size, Feather, Flow, Density. It also has check boxes for Auto Masking and for Showing the Mask.
