Hey Luke..
There's nothing wrong with biscuits/gravy as long as it fits your daily macro-nutrient intake. Personally, I choose to limit my "sweets" intake (though, many people interpret the term "sweets" differently) as it triggers my facial/back acne. For example, I usually have 2-3 sweets a week.. such as ice-cream after training legs, or a nice dessert if I go out to dinner with friends/family.
In regards to calculating your daily macro-nutrient (macros) intake, there are several calculators available on the web for this. A simple Google search should suffice. Personally, I use the IIFYM TDEE calculator, as it seems to be fairly accurate. Depending on your body type, your macros will vary. You should experiment and see what works best for you. I am a mesomorph and try to hit 40/35/25 (protein, carbs, fats) while bulking.
I don't have a strict day-to-day diet plan, as I believe in flexible dieting, so I can't help you there. Hopefully someone else here can shoot one your way. Oh, and download a calorie counter app on your phone (such as MyFitnessPal) if you want to track calories.
