For pure gochari vidhi and its prohibitions, the main texts are usually found in sādhu-ācār literature, not in ordinary householder practice.

If you mean ascetic gochari vidhi

Look into these Jain texts:

• Mūlācāra — especially in the Digambar tradition
• Bhagavatī Ārādhanā
• Ācārāṅga Sūtra — conduct of monks, including careful alms-related conduct
• Pañcāśaka / related monastic conduct texts — in some traditions

If you mean duties and restrictions for a lay Jain commoner

Then the relevant books are usually Śrāvakācāra texts, such as:

• Ratnakaraṇḍa Śrāvakācāra
• Upāsakadaśā
• Other śrāvak dharma manuals in your tradition

Simple guidance

• Gochari vidhi = mostly for sādhu/sādhvī
• Tasks and conduct of a commoner = mostly in Śrāvakācāra

If you want, I can also give you the exact book names by Digambar and Shwetambar tradition separately.
