Etops or any other current republic folks - any thoughts on training? I'm in St. Louis May 30th to June 7. I'm quite sure there is more training, but they haven't told me what, when or where.

I'm assuming business casual attire is appropriate?
Any thoughts on things I might need I wouldn't think of?
Is there time between the sim and IOE or straight in (do I need to take a uniform, which I haven't yet had the opportunity to order)?
Anyone know what is the jr. base for Shuttle FOs?

Thanks in advance!
