Aww, what a sweet heart! His coat makes me think of a Australian Shepherd but his face doesn't look Aussie at all.
The keys to training is to reinforce anything your puppy does that you like. Then ignore the things he does that you don't like (like barking, nipping, whining). Punishment should always be based on taking something away and not adding anything negative. For example, if he nips, no more play time for 5 minutes. If he barks (at ANY point) you walk away calmly to let him know you're not interested. Never hit or yell at the dog as this only shows that you are aggressive and cannot be trusted.
By rewarding him and giving him lots of love and attention you become the most rewarding thing in his life. That is how you make him comfortable with you.
Over the next 2 months be sure to take him anywhere and everywhere you can. You want him to be well socialized before 4 months. The vet will probably tell you to keep him in your enclosed yard but this will lead to many behavior issues. Take him on walks (make sure he walks directly beside you). Take him to the pet store. Take him on a car ride. Take him to your parents house. Take him near busy streets. Run the vacuum. This is all called socializing and it MUST be done VERY young. You want him to be used to anything that could happen.
The first things you teach him should be calm behaviors and default behaviors. For example, give him treats every time you find him laying down and say down. Eventually he will learn the cue down and learn that laying down gets him treats. Give him treats for sitting. Have him sit at the door and wait for a release. have him sit to great people. Things like that. Do not make the first things you teach him default behaviors that are tricks like paw, up, roll over, jump, etc. When a dog is stressed or excited they offer default behaviors and a stressed/excited dog throwing their paw at someone, rolling over, and jumping could easily hurt themselves or someone else.
If you have a puppy who is overly energetic and hard to calm down work on using calming signals with him. Lower to his height and yawn loudly, look around giving fleeting glances, lick your lips, and lower your head. Then give him long slow stroking pets. These will all tell your puppy you are calming down so he should, too.
Teach your puppy how to be alone. Set up an exercise pen or puppy proofed room for him. It should be in a well trafficked area so he can see you most of the day. In the pen cover the whole floor with pads (do not reinforce for using the pads) place a small amount of water, a small plastic crate with no door and a dirty shirt and a frozen KONG in it, and food during meal times. This is where your puppy will be any time you are not expressly watching him (including when you go to work. A puppy that small can only be left in a crate maybe 2-3 hours without risking an accident. You would much rather have an accident on the puppy pads that you will have to clean up when you come home than have a puppy who is used to peeing in the crate and sitting in it. If he is used to sitting in his urine then he will continue to pee in the crate and sit in it.). It will keep him from having accidents all over your house as well as slowly start to teach him some independence.
Another independence exercise is to start by having him somewhere sitting and slowly backing away. If he stays quiet and still give him a treat. Gradually take a step farther and farther each time until you're stepping into another room, closing the door for a second, then longer. Then start to put him in the crate for these exercises to teach him being left in the crate isn't a big deal.
When crate training try to make the crate super awesome, comfortable, and stimulating. Every day before going into the crate he needs to be thoroughly exercised and tired. Crate means nap time and no one wants a nap when they're full of energy. Do not leave him crated longer than you should. Always keep the crate in a trafficked area (bedroom at night or living room during the day). NEVER let him out of the crate, look his direction, move in his direction, give him food, or touch him while he is whining/barking. Crate him at random times for random durations (not only when you're at work for 8 hours). Before you leave every morning ignore him for 10 minutes then put him in the crate (or exercise pen while he's still young). Wait 10 minutes then leave. When you come home ignore him for 10 minutes then let him out if he is being calm and quiet. If not continue to ignore him until he is. Once he comes out he will need lots of exercise and stimulation to tire him again before bed time.
