Replying to New Skier Needs Help!

Hello everyone. I have been snowboarding for going on 10 years now, but I have decided to make the switch after hanging out with some freestyle skiers. I am currently looking into getting my first pair of twin tips and I found a pair of Line 1260's for a very good price. The questions I have are, I am 5'11 and 165lbs and these skis are 164cm so are they big enough for me? I was also curious about bindings. Do any and all bindings work on any and all skis? I was hoping to be able to do the bindings myself since I probably wont order from the same website, so are bindings mountable at home or does a shop have to do it? Thanks for the help.
