For active duplicate you don't need to do this.
1. while using active database duplicate, do we need to set cluster_database=FALSE in spfile clause and create standby,next change it back to TRUE at standby. Or we don't need to touch it. And also do we need to include instance_number parameter
No, it should work. Simple example here :
2. We are using OMF, can we use log_file_name_convert parameter in spfile clause of duplicate. Documentation says log_file_name_convert cannot be used if standby is going to have OMF. Because we have 5 groups for each thread, which are on 5 different disk groups. When standby is created all the logs are created in only one disk group pointed by db_create_online_file_dest_1.
3. To enable force logging at primary do we need to shutdown the database?

For question#2, i couldn't able to find answer in the links you provided. If standby is going to have OMF enabled then by using log_file_name_convert gives invalid file names, according to the oracle documentation. I am confused because i have seen few say it works and few doesn't work.
Can anyone please provide me solution.
