Hi TS, mind if I use your thread and ask some experts here regarding my problems too?

By the way, I'm 17 years old too this year, and since I'm done with my SPM, I'd already planned to increase my strength and muscle mass as I'm very skinny. Few days ago, I have already started my daily training regime, here they are:
-Morning: Constant running on a treadmill and and lifting 10kg of dumbbell(10kg in each hand, so a total of 20kg).
-Evening: Pumping for 5 times(10 reps in each time, so a total of 50 pumpings) and 50 times of sit-ups in one go, training my hand-grippers for 50 reps
in one go.
-Late evening before dinner: 50 reps of training in hand-grippers and 20 reps of lifting dumbbell.
So far, I've found out that my strength trainings are quite efficient, until a day before. I had realised that when I was exercising with my hand -grippers, I realised that my palm didn't feel hurt no more. The same goes when I was lifting dumbbell, I didn't feel sore or pain in my forearm and biceps like I used to feel.
My question is, do I need to further increase the weight for my dumbbell(from 10kg per hand to 15kg) or to increase my reps in hand-gripping training(from 50 reps to maximum of 80 reps in one go)? Seriously, I need someone to guide me as I come to feel that my body has already acclimatise to these training regime, as I don't even sweat even one drop when I was doing these training.
And one more thing, from the day one when I started training, I have been eating/drinking:
-3 hard-boiled egg and a glass of milk for my breakfast
-various meat(fish,chicken,prawns) for my lunch and dinner
-a glass of milk before I go to bed
Now my question is, do I need to increase the intake of hard-boiled eggs or any other protein diet per day? I'm thinking of saving up my money, so that means no energy drink or any protein powders for me. Any explanations and answers to my questions will be fully appreciated, thanks.
