It seems to me that you're way ahead and now lonely there on the top, I recommend you farm for your crafting and try sell some stuff for cash, make an alternative character to enjoy that class story plus he/she can be part of your legacy thingy once it gets out AND you'll have an extra crafter... if it's too early to do all the sidequests then mix it up with PvP and space combat (I love the space combat).
You could also make an opposite faction roll just for the story (nothing serious), I think they can be a part of your legacy as well and you'll have a whole new world to explore and enjoy with new quests
Eventually there'll be lot more people reaching you and you can do flash, operations or whatever your heart desire
P.S. as someone said sharding won't last, they'll decrease or remove it eventually.
