You are completely broke, since by selling all the other stuff you mentioned will not even get you to 20m, which is roughly what a proper power armor set (subj/arma/bandos) costs. I suggest you restart the gp duping machine MtK immediately and you should do ALL gp producing dailies, because currently, you are worse than poor. Before you get a nex set & T9 weapons, you can forget about making money through bossing; when you save up enough for a gwd power set, you should be able to do some weak (and not as profitable) bosses, such as glacors, gwd & qbd, which should take care of your money problems for the time. By the way, as Q suggested, you should focus on ports. After a month or a few, you will have PoP armor, which should by then suffice for tanking normal bosses, like nex or kk.
