Please give a brief overview of why each of the texts you mention are considered important acc. to VisistAdvaita Siddhanta (for instance due to its historical importance and/or acute philosophical insights and/or elegant exposition, etc,.)

Answer 1

Actually Ramanujacharya has written three commentaries on Brahma Sutra:

• Sri Bhashhya (श्री भाष्य​)
• Veanta Sara (वेदान्त​ सार​)
• Vedanta Dipa (वेदान्त​ दीप​)

Apart from Sri Bhashya, One of the important work is Vedartha Samgraha (वेदार्थ​ संग्रह​).

श्रीभाष्यकृद-उपन्यस्तो यः श्रीशैलपतेः पुरः ।
वेदार्थसङ्ग्रहस्यास्य कुर्मः तात्पर्यदीपिकाम् ॥

Vedartha Sangraha contains all the philosophical tents preached in the Upanishads. According to Ramanujacharya, all the texts needs to be interpreted properly to seek the correct truth since he was disagree with some aspects of Advaita. That's why in order to know and understand the true meanings of Upanishads, to overcome the difficulty in the interpretation, he has written a work called Vedartha Sangraha. It embodies a comprehensive and synoptic interpretation of the deepest insights of the Upanishads and also debates with previous works on Vedanta.

You can read the Overview of Vedartha Sangraha at Ramanuja.org.

Prof. M. Hiriyanna describes it as
“an independent treatise explaining in a masterly way his philosophic position, and pointing out the basis for it in the Upanishads.”
