Questions About WWE World/SuperStore

So from what it looks like The SuperStore end is free to the public if im correct on that. But The other question i have is does Everything else that apart of the World/Superstore expirence require a Ticket to the World from fanatics? Or is the Tickets from fanatics for only some exclusive stuff? Plus on top of that Are the Superstars that are gonna be there for Signings/Photo Op the tickets for that separate from the world tickets or are they apart of those tickets?
