Replying to Which ski binding/pole/boot?

I'm looking for a new ski setup for this season. I'm 16 y/o and a intermidiate-adv skier. I like to ski all over the mountain, powder, park, carving etc. I'm 65kg (145lbs) and 175cm (5ft 9).

I will probably go for the bent chetler 100 for my skis. But I don't know which ski bindings, poler or boots I should get. I can find many used ski boots, should I buy used or new.

I've been looking at the Salomon warden 11 or the marker squire 11 id, for bindings. Any other recommendations?

For ski poles I've consider the adjustable line paintbrush.
