First you must have HardSPL on your device
Then it will depends on your preference:
1. If you choose RBSN, then you will need to install the shipped ROM first
2. If you choose NRBS, then you can directly flash the ROM
Last you can flash the Radio ROM on your choice (the latest version is 1.56.70.11)

Note:
You must follow the upgrade guidance from mrvanx
Read more about RBSN/NRBS in the Wiki

Good luck man

No, you only need to flash it once.
Each chef will put such info, whether is it RSBN or NRBS.
