The instrument time question is kinda a trick one, they want to here that you have been in a sim alot or doing a lot of actual flying. For me, I instructed at Pan Am, they allow us to get as much free sim time as we need. To answer your question, for yourself you should feel confident with your skills but no matter what the case is say you have good skills.

For the clothes choice, I went with a black three button suit, white shirt and a dark conservative tie. They want you to look professional.

I am very excited to be part of the team and hope to meet some of you out there to.
