Have you looked up any dog and puppy sites? Look up Husky groups and clubs as well, there are tons of really informative sites out there to help you along with your puppy training.
When using the crate, yes your must close the dog inside. Of course he will not like it! That's why it's an effective punishment!!! This is where you have to be strong and hold your end. If your pooch is supposed to be in there for 20 min, then put him in for 20 and IGNORE him. Unless there is something wrong with the crate, he won't be able to hurt himself.
Puppys go poo quite often and it can vary by size, type of food, etc... Generally a min. of 2 up to 6 a day!!! Be ready!!!
