I am on my second round of having a puppy. I sent an e-mail to my breeder at 1 a.m. myself the other day with the same crying-in-the-crate question you did and I am at home all day with my puppy at this point so it's not just you being gone. Moving the crate into our bedroom has basically solved the problem. He whines at bedtime for about 2 minutes and then again after he pees at 3 a.m. (He's only 9 weeks) and this morning he slept until 7:45! Maybe you could find a smaller crate just for this puppy stage and then later he could sleep on your bedroom floor or he might be fine with sleeping elsewhere by that time.
For the walking, have you looked into a gentle leader? It might have a calming effect on him. It was the only thing that really worked with one of my dogs.
As for the crazy hyper part, the more games/training you do with him, the more tired he'll get. Try a 5 minute game of laser tag (watch out for the light being near his eyes) while you're winding down with a glass of wine when you get home. Or, how about 5 minutes of trick training while you are cooking dinner. My dogs love a game of hide-and-seek in the house and the combined mental stimulation and physical exercise really works. There are lots of websites that can give you "tricks" and games that provide both the mental and physical stimulation they need.
Remember that puppies have an adolescence just like humans. Most dogs calm down as they age.
