Pretty much could have answered all your own questions by searching through hdrol logs, but i'm in a good mood this morning so i'll help a brother out.
First off, your tribulus and miraforte should be used and not bought again. Don't waste your money or time. 1 bottle of H-Drol will be plenty for your first cycle, you want to run it at 50mg daily for 4 weeks. You can get away with an OTC PCT for H-Drol, i would recommend Triazole and maybe some DAA, but definitely Triazole. You don't need cycle assist or PCT assist products, but if you have a ton of money to spend or you got the hook up on them they can really help. All you really need is some NAC on cycle, you can get this in SNS's Liver Assist XT. You shouldn't need to worry about gyno from H-Drol, unless you have a pre-existing condition or are prone to symptoms.
When you're on steroids you get the added effect of increased muscle regeneration. Use this to your advantage. If you're running a traditional split where you only hit a muscle group once a week, switch it to twice a week and push yourself. It will be a bit tough and weird at first, but you should make the most of your cycle. Check out Layne Norton's PHAT routine, it's killer and will really help you explode some new growth. As far as diet goes, if you're not tracking calories and making sure you're eating enough over maintenance you won't grow that much. If you're not eating enough post cycle you're going to lose the weight you've gained. Simple as that.
