Here comes the lady: O, so light a foot
When Juliet rushes into Friar Laurence's cell to marry Romeo, the Friar makes a big deal about the fragility and fleetingness of worldly pleasure (a young lover's "vanity"). But (of course) there's another meaning: Stephen Greenblatt tells us that, when Friar Laurence says Juliet's "light" foot won't "wear out the everlasting flint," he means that she will never "endure or subdue the hard road of life" (source).

What's here? a cup, closed in my true love's hand?
Juliet thinks suicide will let her be with Romeo forever, which… well, whether or not this is true depends on how you feel about the afterlife.

Juliet denies the passing of time (made evident by the sunrise and the sound of the morning birds twittering) because she knows that the passing of time means that Romeo's going to have to jet. Brain Snack: this kind of poem is called an "aubade," or "morning song."
