Replying to Gear Suggestions... 1st pair of twintips

Hey guys I'm looking at getting a completely new setup for next session and wanted some other opinions because I have never bought ski gear before, I have always rented.
A little background, I have been skiing for 10 years (2 in the park), I ski southern NJ so no powder or insanely large jumps, I weigh 130 pounds. I am 5' 5" as of right now, I'll probably be 5' 7" by winter. I am decent at park the biggest jump at my mountain is 55' stepdown and I have hit it. My rail game is bad but I can do most rails that aren't curved or kinked.
I am looking for a good 100% park ski. I'm looking at Afterbangs and Amplid Antidogmas. I have no idea what to look for in bindings or boots. I will see a boot fitter but some suggestions for boots would help. It would be great if you guys could suggest ski, bindings, and boots. Price is a factor to. Nothing to expensive because I'm working for all my gear and there aren't many jobs for 14 year old's except babysitting ext. Also what size of ski should I be looking at, my rental gear this year was 146's but I don't know how good the people who match you with rentals are.
I realize that this is a huge post and I would really appreciate legit help.

Thanks
(if I have left some info out that would help with suggestions just tell me, I tried to be thorough but might have missed something)
