Remember that I-129 is filed by the employer, not you. same for the premium processing. So file with the information that that newemployer would be expected to have at the time of the petition.
So, they are filing for a TN for you with company B, while you are employed at A, so it is concurrent TN. You have a TN, so the employer is requesting an extension of that status. You have petitioned a TN before, so merely list the previous petition number(s) as the explanation, no more. No need for firm B to "predict" what another firm will do.
Your family does not have to file I-539 if their TDs still have time, since you are maintaining TN status.
It does not matter who pays for I-129 or premium processing.
by the way, obviously there is some distrust betweeen you and your employer, sicne there is no obligation for TN employer to be "letting immigration know" about your departure. Sounds like they are being a little racist because you are Mexican.
