Is the phrasing of Tahmid (praising Allah) "All praise is due to Allah, by the weight of His Throne, praise that is unending, everlasting, and does not perish, by the number of His creation, the number of His creation continuing by the measure of a billion raised to the power of a billion, and multiples of that by the same measure of a billion raised to the power of a billion" correct?

The guidance of the Messenger of Allah, peace and blessings be upon him, is the best guidance. It has been narrated from him that he said, "Glory be to Allah and praise be to Him, as many as His creation, as much as pleases Him, as much as the weight of His Throne, and as much as the ink of His words," three times. And that these words, if weighed against all the remembrance that has been said since the day, would outweigh them. It is best for a Muslim to limit acts of worship to what has been authentically reported from the Messenger of Allah, peace and blessings be upon him.
