1. Our letter of application was boilerplate written by the notary. I can't remember it's contents but it was quite formal and brief.
2. Yes, you get the BI clearance on the same day. You just pay for it at the time and they consult their computer and print out a slip of paper for you there and then.
3. No I didn't have my passport photocopy authenticated, but I had my original with me for them to examine when I applied.
All the best. As you will see from my previous post, things aren't always what they seem to be, but keep trying and be patient. I get the impression that the new system managed to cut out a little of the under-the-counter stuff for our friends in the BI; but they're back up to speed now and have figured ways to get their hands on some foreigner-sponsored overtime by creating endless committees.
