There's quite a bit to do, but what do you want to do?
There's your class quests, main story line, and random quests which all give good SP now to help you rank up your main to get access to even more class and main story...
The gathering and crafting classes also have stories and such, also they will bump up your physical level (while it exists) quite quickly. It's not that painful to get crafts to 10ish via leves and even minor grinding even if you don't like crafting.
You want stories or you want SP or parties or what? If you want parties, join a LS or group up with folks via your servers forum on here or wherever (quite a few of the very helpful folks on this board are from Istory as well). If you want SP; hit every leve reset, do every mission/quest you can, behests, and try to join parties when possible.
