Avos 2:4 וְאַל תֹּאמַר לִכְשֶׁאִפָּנֶה אֶשְׁנֶה (5785)

(1) The Laws of Tefillin in Detail. Containing 13 Se'ifim:
After putting on one's tallit with tzitzit [on it], one should put on tefillin because [we do mitzvot] in ascending order of holiness. And those who put their tefillin and tallit bags [together] into one bag must take care not to place the tefillin bag on top so that they won't encounter them first and [subsequently] have to put them on before the tallit in order not to skip mitzvot. Rem"a: However, if one has the tefillin ready but does not have a tallit, he does not have to wait for a tallit, rather he puts on the tefillin. When they bring him a tallit, he puts it on [his (the Rem"a's) opinion].

(7) He does not have to wait - Because we don't delay doing a mitzvah. Even though one can argue that he'll be able to perform the mitzvah in the most optimal way later (ie. if he waits till he has tzitzis, he'll be able to put everything on in the proper order), [nevertheless] a mitzvah that can be done now is more beloved. Also, when a frequent practice and an infrequent practice clash, we hold that the frequent practice takes precedence [over the infrequent practice] - but if the frequent practice is not in front of me right now, there is no need to wait. ...

(2) We should only bless regarding the moon on motza'ei Shabbat, when one is drunk and one's clothes are nice. Note: and this is specifically when motza'ei Shabbat is before the 10th of the Hebrew month, in this case we wait untill motza'ei Shabbat. However, if it's after this we don't wait to motza'ei Shabbat, lest there are 2 or 3 or 4 cloudy nights and the moon is invisible, and the time to bless passes. And when we bless the moon during the week, it's good to put on nice clothes (T"H chapter 35). We don't sanctify the moon before Tisha b'Av or before Yom haDin (Maharil), and when Yom Kippur goes out we bless it, since then we exist in a joyful state - but not when Tisha b'Av goes out, or any other fast (my own opinion), and we don't sanctify it on motza'ei Shabbat which falls on Yom Tov (Maharil, laws of Yom Tov). And one fixes their eyes and straightens their legs and blesses (Standing) (Tur) and says three times: "A good sign it will be for all of Israel, Blessed is your Creator etc." Note: and dances three times towards it, and says "Just as I dance, etc", and says "Fear and terror will fall on them, etc" (Shemot 15:16), and again backwards, "Like a stone they will be, etc" three times, and says to one's friend three times "Peace be upon you" (Hagahot haChadashot), and responding to this greeting is like saying it (Tur). And we are accustomed to say "David, King of Israel, lives and exists", since his kingdom is compared to the moon and will in the future be renewed like it. And the assembly of Israel will return and cleave to her Husband, who is the Holy Blessed One, the image of the moon who is renewed with the moon - as it is said, "A sword and a shield is God" (Tehillim 84:12), and therefore we make joys and dance in the sanctification of the month, which is an image of the joy of a wedding. (Bachya, parshat vayeishev, and my own opinion).
