Visiting first orthodox synagogue since decades, not too sure what to expect.

Grew up secular and found an amazing synagogue that serves both reform and conservative community, that I have been active member in for many years now. However last few months I’ve had a nagging feeling to visit an orthodox synagogue on Erev Shabbat, since I haven’t been to one for over 20 years, and I want to prepare myself before I go there for a service. Found an amazing Modern Orthodox synagogue that’s a walking distance from my home. Both rabbis are Ashkenazi, however the community is mixed of Sephardi and Ashkenazi, the Siddurs available are both for Sephardi and Ashkenazi, both from Artscroll. Since I don’t speak Hebrew but can read it, albeit very slowly, I wanted to prepare myself with getting up to speed with reading texts during the Shabbat service.

Is there a particular order the prayers get read out in, or they just follow the Siddur starting from Y’did Nafesh until the last page of Shabbat prayers?

What’s the appropriate dress code for visiting MO synagogue?

How seriously is no-carry rule observed? Anything else I could prepare myself in advance before visiting?

Thank you in advance.
