There are a lot of guides out there for leves, for solo grinding and party grinding. There are quests in every city that award a lot of SP. As you rank up you can meet other people, join a LS, do dungeons...

I think there is a LOT of content out there right now for people that are just starting.

Try YG.com or simply google what i mentioned above.

Try and get to every camp in every area, etc..
