The hump from Kingsmouth to Savage Coast is difficult. The Overlook Hotel is tough. I actually found the quests at Innsmouth Academy to be far more solo-friendly for new arrivals from Kingsmouth.
That being said, do what I did: group the heck up. Make sure the person you're grouped with will be ok with you wanting to watch the quest giver cutscenes and stuff, and then go knock those quests out! You'll end up with a fairly solid set of QL 4-5 gear from that and can build skills much faster and get over the hump.
