There are three parts of the vine that can be injured by frost, the buds, the shoots (including flower clusters), and the trunk. It is hard to assess bud damage without dissecting a few of the buds to look at the tissue (refer to WSU publication below for assessing bud damage). Based on the photos, it looks like the shoots and inflorescences were the parts that were injured. You should inspect the trunk for splitting or cracking.

You will likely see a significant reduction in yield this year, but the vines should recover. Studies out of the University of California have shown that taking no action is often the best approach (refer to this UC article) and that removing damaged shoots did not improve yield, and was not cost-effective. NC State provides advice on managing frost injury based on the stage of growth (refer to this NC State publication). This publication states that if at EL-12 or lower, you should remove severely damaged shoots back to the cordon to force dormant buds to break. It is hard to tell based on the photos, but it looks like you are at about EL-12 where you have 4-6 leaves per shoot that have unfolded, and inflorescences are clearly visible. I suggest you read through the recommendations in the NC State publication and make a decision on whether you want to take action, or do nothing.
