700 x 32c inner tube?

The 700 x 18-23 was just too small you shouldn't have accepted that. The 700 X 25-28 should have been ok. Walmart carries 700 X 25-32 tubes for a little over $4 it will fit my road bike and my hybrid. I always mark the tire before I take it off so I can line up the puncture with the tire. I always find something embedded in the tire. The tire direction wont make much difference on a hybrid tire. You want to make sure you keep the pressure in the range that is printed on the sidewall. Stay away from potholes and jumping curbs. If the hole is in the inside surface check the tim tape. The rear tires are more prone to get flats.
