site for RJ intro- www.crj2.com
travel bag- purty neat at www.stopoverstore.com
Flight case- up to you but look at those at www.stopoverstore.com or you can just get a chart case at www.officemacx.com. i spent all of $60 shipped and its held up great (only 6 months into the RJ)
headet- ebay your way to a telex 850, thats about top of the line. I got mine for $375 and coming from a bose in GA flying its great. The 750 is cheaper but is not ANR. I see vision/hearing as important so you just need to decide if its worth the extra $$ to ya.

beyond that- CONGRATS!
