1: My understanding is that, no, a user account is tied to a homeserver, much like an email address is tied to an email provider; there are plans to make it possible to move or share user ids at some point in the future.

Rooms, on the other hand, are IRC-like in that they aren't associated with any specific server but exist on all servers which have a participant.

2: That's handled by "identity providers" which are sort of outside the core Matrix protocol, and provide a mapping from third-party identifiers (email addresses, phone numbers, personal names, or other identifiers) to matrix user IDs. I don't know what the state of play is for those, really. They exist and have client integration but I think the system is still more of a usability hack than a polished design.

just to clarify on answer 2: identity servers simply map 3PIDs (e.g. email addresses) to MXIDs. They do not provide a directory service; homeservers provide this instead. The only exception is if the identity server implementation gutwrenchs into the rest of the protocol to override directory lookup APIs which would otherwise be provided by the homeserver.
