Question: is puja the most important part of hinduism

Answer: No, Puja rituals are also held by Buddhists and Jains. In Hinduism, puja is done on a variety of occasions, frequency and settings. It may include daily puja done in the home, to occasional temple ceremonies and annual festivals. In other cases, puja is held to mark a few lifetime events such as birth of a baby or a wedding, or to begin a new venture. The two main areas where puja is performed are in the home and at temples to mark certain stages of life, events or some festivals such as Durga Puja and Lakshmi Puja. Puja is not mandatory in Hinduism. It may be a routine daily affair for some Hindus, periodic ritual for some, and rare for other Hindus. In some temples, various pujas may be performed daily at various times of the day; in other temples, it may be occasional.
