restore prod backup in dev server using RMAN

i have a production database (oracle_sid is prod)
i want to clone the prod database to dev environment( oracle_sid is dev) .

i have rman backups in production database. i ftp'ed them to dev environment.

if i restore the backup in dev ,
1. will DBID & oracle_sid be the same in dev and in prod??

-- Also, i am in current dev box: if i issue
2. rman target sys/sys@prod auxillary /   -- will this complete the process??

3. is it essential i know the sys password on PRod ?? i have dbaoper user password ..  will that be sufficient ?

basically, my doubt is  -- i have already got a dev database up & running on the DEV server.
i want that to be "overwritten" with the prod backup..

i am following this doc.. i have attached the doc.

am i following the right thing.. ???

( I have already got the init file ,,, but the doc says to create a init file ??
please advice...

Having scanned to document before I deleted it, I say it is probably safe to follow since it came directly from Oracle.

If you already created an init.ora file, you can probably skip the creation step.
