All dogs chew, hence they invented dog chews! But just like a child will play with the box the expensive xmas present came in rather than the present, dogs will chew anything other than a dog chew.
However, the first and foremost thing to bear in mind is that dogs are simple animals, how many times have I seen puppies chewing slippers and then later owners getting mad at their dog for chewing their finest italian brogues! So its got to be the same message from day one!
You can only "punish" your dog if it does something in your presence, and it must be immediate, usually a harsh tone of voice and a "bad dog" will suffice. It is never acceptable to cause your animal pain or suffering.
With regards to chewing then it must have specific items to chew, and these should be specialy designed chews and not household items, as we don't want the dog becoming confused. Theres lots to chose from, from rope type affairs that clean teeth to the old pigs ear. You should try and play with your dog with the chew, and then hold the chew while she chews it, send a positive message that chewing this particular thing is good.
The key to all animal training is positive and negative praise, reward the good behaviour enthusiastically, and have a short harsh "bad dog" for the bad behaviour.
