You've mentioned you owned a puppy before and chew toys are important, I'd also suggest getting a product called Bitter Apple, or something similar. We used to keep the puppy from chewing on furniture, shoes, and assorted body parts. It has a really bad taste and it stopped the inappropriate chewing very quickly.
I'd suggest looking into local training classes they'll help with potty training, socialization and basic commands.
I've always wanted a chocolate lab. Congratulations and good luck with the puppy.
