There's a real nice summary on Curse of what you need to do to get rep when the 2.4 patch hits and how the gates and quests will progress. Worth a read.

tnx TL :D now i got some reading to do at work :D
Also just to say, don't worry about worrying how to get into The New island, Flight paths at Ironforge and Silvermoon fly you there, from what i rememeber you get out of Ironforge gates then 'teleport' to the gryphon flying around the island before reaching the Small base
