Sonnet 130 is in more of a humorous fashion. In short, Shakespeare is saying his mistress' beauty is not that of a goddess, and she cannot be compared to the beauty of one.

Imperfect. Ugly
A bad smell.
Shakespeare says: 'My mistress's eyes are nothing like the sun'
In sonnet 130, the speaker mentions that his mistress's cheeks are not as red as coral. He is highlighting the honesty in his love by comparing her to realistic, ordinary things rather than using exaggerated, flowery language.
An example of hyperbole in Sonnet 130 would be "And in some perfumes is there more delight / Than in the breath that from my mistress reeks." The comparison of a mistress's breath to a foul smell is an exaggerated and intentionally unrealistic statement for effect.
His mistress in this poem is his beloved. That is not a particularly obsolete meaning.
