What is a person supposed to study each day?

At minimum, a person is meant to study a passage from Mikrah, Mishnah, and Gemara every day. Therefore, after the parsha of Tamid, the order of the siddur continues with a perek of Mishnah discussing korbonos and a braisa of Rabbi Yishmoel (in place of Gemara) discussing the methods of expounding on the Torah. Since the purpose of saying these passages is to fulfill the mitzvah of talmud Torah, it is best if the reader has a proper understanding of their meaning.

סימן נ, סעיף א וס"ק ב; ביאורים ומוספים דרשו, 3

Can one interrupt between Boruch She’amar and Pesukei D’zimrah?

Boruch She’amar--the brocha which is said before Pesukei D’zimrah--was instituted by the Anshei Knesses Hagedolah. Since it is a brocha over Pesukei D’zimrah, one should immediately begin saying the pesukim upon completing the brocha. One should certainly not talk at that point, as it would be a hefsek between the brocha and the mitzvah. Answering Amen to a brocha, however, is permitted, because Amen is a form of praise like Pesukei D’zimrah.

סעיף ב וס"ק א, ב ו־ד; ביאורים ומוספים דרשו, 3

Can one answer Amen to his own brocha?

The Gemara states that answering Amen to one’s own brochos is reprehensible. Therefore, a person who makes a brocha should not answer Amen if someone else finishes the same brocha at the same time. He may respond to a different brocha that is being completed as he finishes his own. According to the Shulchon Aruch, one may answer Amen to his own brocha if it is a brocha at the end of a tefilah.  Examples include answering Amen to Yishtabach, Shomer Amo Yisroel Lo’ad, and the final brocha of Hallel. Rema holds that one should not answer Amen when he completes these brochos unless there is another person finishing at the same time.

סעיף ג וס"ק ג ו־ה

• There is a longstanding custom to recite the parsha which discusses the Korbon Tamid at the beginning of davening. Some Rishonim use terminology that describes this custom as an obligation.

• It is customary to shuckel (sway) while learning Torah. Shuckeling is reminiscent of Matan Torah, which caused people to tremble.

• The Gemara states that verses which are written in Tanach may not be read by heart. The Rishonim say there are various qualifications to this halacha. 

• Can a person who is in the middle of Pesukei D’zimrah be called for an aliyah?

• Can one say Asher Yatzor in the middle of Pesukei D’zimrah?

• Is it permissible to greet someone during davening?
