To easily get Agility XP, make sure you've leveled up the FreeRunning Adept and FreeRunning Expert skills, which will make climbing worth 40 XP. Head to the Tower and wait until night, when you'll earn twice the usual amount of XP. Head left of the Tower toward a building with barrels at its base. Climb both the barrels and the building. Right at the top, let yourself fall backward so you can climb them again. This should earn you about 120 Agility XP per second.
Once you complete the main story, you will be able to fast travel at certain locations. The poster in your room in the Tower lets you fast travel between the Slums and Old Town. The northern door in the Slums and the northern sewer door in Old Town will let you travel to Antenna.
