Which Skis should i buy?

So I want to get into park/freestyle skiing and i have a couple options on what to choose. I used to ski when i was younger and got down the black diamond slope 1 time. I am 16 years old, 171 cm tall (like 5'7", and about 125 - 130 lb. I found a bunch of deals on evo.com and ski.com, on evo found k2 recoil skis 2012 ($275), Nordica Hot Rod 6.5 Ski Boots 2012 ($140), and Marker 12.0 Free Ski Bindings (90mm Brake) 2010 ($123). Or should i go with Salomon Z 11 Wide Brake Ski Bindings 2012 ($99) from skis.com. Will 90mm bindings fit for the skis? Should I go with 164 cm skis or 169 cm skis? I am growing really fast. Everything especially the skis are really good prices. My uncle in Poland found used rossignol s2 park 09/10 skis (170cm) with bindings. He said he will sell me them for about $150 plus shipping, so lets say about $200 for the used skis and bindings. What do you think i should buy? Or tell me if there are any better skis/deals that would fit me? I think i should but the k2 skis, but my chose is a lot more expensive.
