You can also watch the arrows at the top of the histogram, the change colour as different colours start to clip somewhere in the image. When al the RGB elements are clipping the arrow will turn white (it's grey if no component is clipping). Illustration is below, the black point arrow on left is coloured white to show clipping, the white point arrow is on the right and is coloured grey to show no clipping.
If you click on one of the arrows it becomes framed with a square and as part of the image starts to clip at whichever extreme that area of the image flashes (like the blinkies in the camera LCD).
Personally I pretty much just adjust to my personal taste rather than using these indicators. The adjustments in LR4 have shadow highlight sliders as well as white and black point adjustments. The LR4 just works better in my opinion.
The other way to make localised adjustments is to use the curves adjuster, if you click on the pointer tool (circled in red) you can pick it up and drag it over the image. By clicking at the point you wish to adjust and dragging up or down you can lighten/darken that point in the curve.
