Required Daily Study
Pausing Between Baruch She'amar and the Rest of Pesukei D'zimra
Which Berachos Do Not Get an Amen

Required daily study
A person is required to study some Mikra, Mishna and Gemara every day. To fulfill this obligation, the Geonim instituted the daily recitation of Parshas Hatamid ( Mikra), the perek of Eizehu Mekoman ( Mishna) and the opening passage of Toras Kohanim, the braisa of Rebbe Yishmael (as Gemara). It is necessary to comprehend the content of these passages in order for the recitation to be considered Torah study.
( סימן נ, סעיף א וס"ק ב; ביאורים ומוספים דרשו, 3)

Pausing between Baruch She'amar and the rest of Pesukei D'zimra
The beracha of Baruch Sheamar was instituted by the Anshei Knesses Hagedolah, although the wording does not appear in the Gemara and is recorded first in the writings of the Geonim. Baruch Sheamar is a beracha over pesukei d'zimra and should be said immediately before reciting those pesukim. Ideally, one should not pause for longer than k'dei dibur between the beracha and the pesukim. Likewise, it is forbidden to interrupt between the beracha and the pesukim by speaking. Saying Amen, however, is permitted; like pesukei d'zimra, Amen is a form of praise to Hashem and is therefore not considered an interruption.
( סעיף ב וס"ק א, ב ו־ד; ביאורים ומוספים דרשו, 3)
Which berachos do not get an Amen
Chazal considered it disgraceful for a person to respond Amen to his own beracha. It is even inappropriate to respond to someone else who is simultaneously reciting the same beracha. It is permissible to respond to someone who concludes a different beracha at the same time. According to the Mechaber, the berachos of Yishtabach in Shacharis, Hashkiveinu ( Shomer Amo Yisrael la'ad ) in Ma'ariv, and Yehallelucha after Hallel are exceptions, and an individual should answer Amen after his own beracha in those cases. According to the Rama, these berachos are not exceptions and an individual does not respond Amen to his own beracha in these cases.  If someone else concludes the same beracha along with him, however, he does answer Amen.
( סעיף ג וס"ק ג ו־ה)

  • There is a universal custom to recite the parsha of the korban Tamid before davening Shacharis (and many recite it before Mincha also). This recitation is considered obligatory for men and women alike.
  • Some poskim recommend shukeling when davening in  fulfillment of the verse "My entire being will declare 'Hashem, who is like You?'". Other poskim are opposed to this custom because tefilla  is to be recited as though standing before a human king, when any movement is improper.
  • It is generally forbidden to recite passages of the Written Torah by heart. The poskim discuss whether this rule is limited to public ceremonies (e.g. kriyas haTorah) or if it applies to individuals also.

  • Interrupting pesukei d'zimra for an aliyah

  • Interrupting pesukei d'zimra for a davar sheb'kedusha

  • Responding Amen while davening
