1)C, send out a quick battlecruiser force to smash a Scandinavian convoy or two. This is less likely to get you in trouble than an attack on Dover and will both hone their skills and greatly improve morale, as long as things don't turn sour anyway...

2)B, scale back wireless or change encryption schemes. It won't stop the sailors from screwing around while on shore leave, but will help to break the monotony, perhaps improving morale or at least their mental edge, and be beneficial to future operations.

3)A or B, if the final decision is to attack a Sandinavian convoy or Dover definately send out the zeppelins, you will already have shown that you are up to something so there is no great risk in sending out the zeppelins. Otherwise keep them at home for now.

4)Keep the old ships at home for now, but don't completely resign them to the mothballs, they could be handy later on as a diversionary force.

5) Definately recall the Baltic fleet, they are good enough to help alleviate the English navy's sheer weight of numbers.
