Welcome and congrats!!!!
I Know the feeling. I have been in awww with Riley since the moment I went and picked him up..... He has been so unbelievably good and such a sweety.
I took him to a puppy beginning class at PetSmart, immediately. I have had two other dogs, in the past, whom I had taken to PetSmart. I pretty much knew what to do in order to teach him commands.... But, I had a coupon for it so I signed him up just to get him out and about and to get him a little socialized. He did really well in it. He will be 1-year, next week.... The weather here is getting nice and I am starting to look and see what kind of classes there are around to sign him up for. He loves training and doing tricks.
Good Luck!
