Hi Avinash,
Sorry, I don't have such documentation. However let me suggest you to follow this one instead. This is the official guide created by SAP.
Regarding your other question:
Basically the SRM-MDM and the NW MDM are different products. The SRM-MDM UI uses the features and services which are provided by MDM. So if you would like to have an SRM-MDM Catalog then you need to install MDM as well.
You can find here a useful Wiki, and the documentation page of SRM-MDM Catalog.
Regards,
Viktor
