Hi Virajrao,
First of all congrats on receiving your passports back. Ideally, your passport, COPR docs, WP, Driving License (for address proof for sending PR cards) should be enough. But seniors on the forum have also suggested the following. Please bear in mind that the documents listed below are optional and are the docs that I took, but was not asked for at all while doing landing.
1. Pay stub (last 3 months)
2. Bank statement (last 3 months)
3. Marriage certificate copy (if landing with spouse)
4. Children birth certificate (if landing with kids)
Hope, the info helps. All the best for your landing !!!
