Let me preclude this by saying I love glucose disposal agents, have tried many in the past, and will be using Glycobol in about a week. However if you aren't careful with your calories, you will still put on fat. These products help, but they're not magic. So please don't get carried away with your caloric intake.
As for products to help you PCT, test boosters are a great choice. Divanil is particularly effective, especially with an AI. Some people really like Arachidonic Acid. Just make sure you got the staples like Creatine, Beta Alanine, Green Tea, Fish Oils, etc and perhaps look into something like ALCAR and ALA. Also you've discovered Glycobol, great choice there too.
