Is it enough for one to read the Bhagavad Gita alone among the Itihasa and Puranas as it contains Karma Yoga, Bhakti Yoga, and Gnana Yoga? Will this lead to salvation?

Bhagavad Gita mentions various Vedanta Gnana, Sharanagati, etc. hence it is a must to learn Bhagavad Gita. Will it lead to Moksha? The answer is, it shall grant the required knowledge and invoke the thought that one has to perform sharanagati to attain Moksha.
