Gatherbuddy - Flight paths and hearthstones!

[Unknown]

Okies dokie - I'm not new at this, but I am however, a little confused as to which (new) zone requires which hearthstone and which flightpoints my toon needs to have learned to go and mail or use my guild bank.

I'm assuming;

Deepholme - Mails and repairs from Deepholme itself
Uldum - Needs flightpath and hearth to Sillithus
Twilight Highlands - repairs from Twilight highlands (no HS needed?)
Mouny Hyjal - repairs and mails from Hyjal (no HS needed?)

If someone could clarify the above (or rectify any mistakes!), then I'd be most appreciative.

Cheers!
