First time puppy training seeking advice

Hi we have a 5 month old puppy who is very loving and friendly to all people and other dogs and the main things we are trying to focus on right now and would appreciate advice about are switching pad trained (mostly)to outdoor potty training ,he has a problem with jumping up on people which most don't mind but he also tries to jump and play with kids , pawing like he likes to use his hands a lot but it scratches, oh and he pulls really hard on the leash . Any advice is appreciated. I've done research but asking for advice on here can't hurt and this is our first dog .
