The 'City-Ticket' in Bremen covers public transport in fare zones 100 and 101.
If you live within one of those zones, the ticket will cover the trip from your home to Bremen main station.

Yes, because "tarifliche Gleichstellung" (station grouping) applies. In such a case, you get a ticket that does not have the name of a specific station as start or endpoint, but the name of a station group. You can see that this applies to your case because the startpoint is listed as "Bremen" (the name of a station group) instead of "Bremen Hbf" (the name of a specific station). So you can start your trip at all stations in the station group of Bremen, which you can find on page 7 and 8 of this list in the second-to-last column. In the case of Bremen, the station group goes as far north as Bremen-Farge.
Explained differently, station grouping means that for long-distance tickets (> 100km) all stations in certain sets of stations are treated as if they were identical. The regulations for station groups are in this PDF in Section 3.7.
As mentioned by Tor-Einar, the City-Ticket option often also allows traveling to your startpoint. There are some important differences though:
