The Amidah Prayer

I hope to visit Israel this summer. Should I say “morid hatal” in Shemoneh Esrei like Israelis, and should I continue to say Baruch Hashem L’olam at Ma’ariv?

Does Yehiyu L’ratzon come before or after Elokai Netzor and/or personal requests at the end of Shemoneh Esrei?

People are davening in their homes, again. Is Davening in front of a mirror problematic?

I have seen some chazanim wait, during their Modim, at “l’olam va’ed” for the tzibbur to finish Modim D’Rabanan. That seems to make the most sense, so everyone can hear all of Modim. Should everyone be doing that?

When minyanim closed, I started davening vatikin (starting Shemoneh Esrei (=SE) at hanetz hachama (sunrise=netz)). If I do not know precisely when netz is, is it better to err on the side of starting SE before or after netz?

What types of requests are prohibited on Shabbat? Is davening for peace and tranquility in one’s own words permitted?

Following our grandchild’s birth, I have been adding personal thanks to HaShem in “Modim.” Is it appropriate to do so on Shabbat?
