During my 1st yr of officiating basketball I found myself listening to everyone and their opinions of what the rule is/was... I ultimately found out that rarely did a fan have a clue what the actual rule was, some coaches/players had a vague understanding and most officials knew the rules.
Please note I said most officials. There are some officials that have not opened the rulebook since "Gee, I don't remember when..."
Bottom Line: Keep your nose in your rulebook and look for clarification here. It is the best way to learn/improve. I learn something about officiating just about everytime I read through the threads here.
Keep at it!
