Numerous authorities find it acceptable to begin a sentence with the conjunction and. For example, the Chicago Manual of Style’s Rule 5.203 says, “There is a widespread belief—one with no historical or grammatical foundation—that it is an error to begin a sentence with a conjunction such as and, but, or so. In fact, a substantial percentage (often as many as 10 percent) of the sentences in first-rate writing begin with conjunctions. It has been so for centuries, and even the most conservative grammarians have followed this practice. Charles Allen Lloyd’s words from 1938 fairly sum up the situation as it stands even today:
Next to the groundless notion that it is incorrect to end an English sentence with a preposition, perhaps the most widespread of the many false beliefs about the use of our language is the equally groundless notion that it is incorrect to begin one with “but” or “and.” As in the case of the superstition about the prepositional ending, no textbook supports it, but apparently about half of our teachers of English go out of their way to handicap their pupils by inculcating it. One cannot help wondering whether those who teach such a monstrous doctrine ever read any English themselves.”

Your verb conjugation is fine.

Yoda does speak a lot with inversion, but many writers through the years have done the same. It’s simply a technique that Yoda claimed a bigger share of through pop culture.
