I would say this is some good advice
I myself dont like the line afterbangs they are made like a skate board so they are a bit heavyer than most park skis and as your new if you fall alot you will chip the fuck out of them, the k2 domains are the way to go, rocker is a fairly new thing to park skis and is like cheating.
You should go to a good boot fitter like surfoot, i had shin bang badly in salomon spk's and pros's because i went to a shit boot fitter and was put in a wide boot 1 size to big when i have a skinny foot, full tilt boots changed my life (custum liners and foot beds helped too,+ they blew the ankle out and grinded a few bits, GO TO A BOOT FITTER) the full tilt hot dogger is going be your best choice for park if it fits your foot
bindings i would say marker griffions
poles, take a look at the scott team pole,
also if you wana go the hole hog take a look at saga, orage,or armarda for outwear
