First of all, you should be using the right ancillaries on cycle, which are an AI and cabergoline. Since you already have arimidex, use it at 0.5 mgs EOD from the first day of the cycle, and do the same thing with cabergoline at 0.25 mgs, either EOD, or E3D.
Then, for PCT I really like the layout of the perfect PCT as suggested by @muskate and @stevesmi. And sincerely, I believe that nolvadex has a good place in modern PCT, as it works great in synergy with clomid. Finally, don't use HCG - it has very doubtful benefits, and yet it can cause such side effects as gyno and suppression. For me, HCGenerate ES is a much better alternative.
