I am traveling to Greece with a group, and I don’t have a passport or visa at all. Do I have to apply for it myself, or should the travel agency cover all these things? Thank you.

Generally, travel agencies will provide visa processing services, but they need to pay a certain service fee (depending on the country, travel agencies charge different service fees for different places). You need to provide the travel agency with the original passport valid for more than six months, 2 passport photos (fill in 2 visa application forms in English capital letters), a copy of the front and back of the ID card, and a copy of the first page of the passport.
