Fig trees can live to be 200 years old so  old age is not the cause of a poor harvest. The most common reasons for lack of figs is the tree is too young or too little or too much water. A high nitrogen fertilizer such as one used on the lawn could also cause foliage but no fruit. I would trim it back hard next spring and make sure lawn food is kept away from the roots. As for your tomatoes, pick when you see a dark green star on the blossom end and store in cool, dry spot without letting them touch one another. Tomatoes do not need sunlight to ripen after harvest if they are at the green star stage of development.  You can also upright the entire plant and hang from rafter of a garage or shed and fruit still hanging on the plant will ripen over time. Keep growing, Marianne Binetti
