Based on my interpretation of what I've read in the Gita the Mahabharta is the whole of the Scriptures in Sanatana Dharma. Correct?
Mahabarata is one of the great histories Maha meaning Great and Bharata is the old name for the entire Indian continenent them much larger that the India of today . Mahabarata is the great epic which gives the account of the family conflicts leading up to the great battle at Kurukshetra this was the war over seen by lord Krsna and describes the position of Bharata athe end of Dvaparayuga just before the onset of Kaliyuga , ...this is an important text for Vaisnavas although it is not the only one there are other histories contained in Bhagavatm which gives accounts of all the many incarnations of Visnu there is also the Ramayana loved by many Hindus , ....
Mahabarata is particularly favored because it contains the Bahgavad Gita,
The Song of God , ....Krsna's Discourse given to Arjuna on the Battle feild , ...A Vaisnava treats this discourse as an entire code by which to live his lifa and understand his relationship to the Supreme .
How many different Scriptures are there in the repertoire (If you want to call it that) of Sanatana Dharma?
Manny many , ... as Vaisnava we were taught to use the term Sanatana Dharma and certainly veiw the the Gita as a tretise on Sanatana Dharma ...
our eternal relidgious duties , ...not all Hindu associate them selves with Sanatana Dharma and have texts particular to their own traditions
Mahabarata , ...although there are many other texts that I also adore
