tbh m8 I personally wouldn't cut the cardio out of your routine just eat more calories to make up for it!
Its not going to effect you that much in fact just ask James oh here as he is a bit of a cardio freak as he told me lol ;) (gotta love James)
Also with your diet have a look on here about how to work out how much calories you need and then work out your Macros that you need in terms of Proteins Carbs and yes even fats as you are going to need them also!
As for supps tbh i wouldn't bother with too many of them just spend your money on quality Foods and remember if you eat big, train Hard and Have enough rest you will get BIGGER than you ever thought possible and you have got to remember that all's a supp is like in the name its a SUPPLEMENT to your diet and if you have a good enough diet for the first part of your training you wont need them m8 believe me!
Like i said just spend your money on things like quality Meats, Quality fish etc and eat good, Train Hard and Be Strong!
