Just a few facts about the flute, I bought it used, and it came with some stuff unknown to me (see first bullet) along with a cleaning cloth and cleaning rod. It's a Powell Sonare 501 Open (french) Hole B foot Offset G Y arms Silver Headjoint Nickel Body.
My questions are:

•I'm not exactly sure what the above is, but I believe the paper thing is cigarette paper? Not entirely sure.
•What steps should I take/what should I buy to protect the silver headjoint, because I've only played nickel flutes since I've started.
•What brand of plugs do you recommend?
•Are there any other acessories you recommend other than cleaning rod, cleaning cloth, plugs, and cigarette paper?
Thank you so much in advance.
