Repeating what

You can only use AA miles to upgrade AA flights operated by AA metal. AA codeshares operated by other carriers ie CX do not apply! Whereas if you have Asiamiles, you can use them to upgrade CX, KA, BA and AA flights !
CX has only one MPC number for all MPC members. There are no special numbers for elites, but calls are prioritised according to tier levels. However, the number is for MPC members only.
Yes, having any other FF elite number will not work on the special Marco Polo Club phone lines.
