To some extent, the current scale of the time ruler determines the precision of the edits you make in the Timeline window: the closer you're zoomed in, the easier it is to make precise adjustments. When your work is focused on fine-tuning edits, however, you should take advantage of a window optimized for trimming tasks: the aptly named Trim window. Like the Monitor window, the Trim window has two views. But instead of a source view and a program view, the Trim window shows two adjacent clips in the sequence. The Out point of the first clip appears on the left; the In point of the second clip appears on the right. An array of controls allows you to perform precise ripple and rolling edits.
