What is the meaning of "va'Ehyeh Etzlo Amon"?
Tanchuma (Bereishis 1): We read Amon like Uman; the Torah was Hashem's Kli to make Ma'ase Bereishis. Ma'alos ha'Torah - therefore, one who engages in Torah, it is as if he built palaces above and below, and made Shalom in the entourages above and below (Sanhedrin 99b).
Rashi: [Chachmah] was raised by Him. [Amon] it is an expression of raising, like "ha'Emunim Alei Sola" (Eichah 4:5).
Malbim: The verse depicts that Chachmah was already raised in Hashem's lap. Initially it was like a delightful child - He carried it like one who raises an infant, and constantly delights in him. He did not yet do any actions to play in front of Him, just He delighted in [Chachmah].
What is "[Sha'ashu'im] Yom Yom"?
Rashi: It is 2000 years.
Malbim: Afterwards, He created time, and [Chachmah] frolicked in front of Him constantly. Hashem made Ma'ase Bereishis via Chachmah during all [six] days of creation, new creations every day. The times and orders changed with every elevation of the creation that was carried out in practice. This was Simchah in front of Him, that everything was according to Chachmah.
