3. Unfortunately USPS does not track China Post Register Airmail in USA since last year. So the only way you know that a parcel arrive is if the Mailman leave you a card to pick up the parcel. It's register mail so you have to sign for it.

4. Maybe you should contact your seller as soon as possible and tell him you have not receive your parcel yet. Please provide the seller with the following tracking so he understand what you are talking about;
