Many thanks! You answered every question I had!

Just bought a 90 day time card, had a few questions. When the ninety days is over, will I be a preferred player, or go back to f2p? Second, if I do go back to f2p, will I keep access to higher level toons (Those above 60), and the expansions? Finally, if I revert to f2p, and I have more than 1 crew skill, will it auto-unlearn them, or will they stay as learned skills. The information I've found regarding this has been varied, so I was hoping for some concrete answers, thanks in advance.
