Replying to Learning to Ski, newschool rocks

Hi Guys.
I'm completely new to skiing and hope to have a few lessons to get the hang of it then heading off to Austria in March to have a go at the real thing.
I've experience ice-skating and roller-blading so at least I can hopefully pizza my way down :D
Just a few questions about Newschool skiing as it's tough to get my head around all the different parts of skiing at once.
What're the best type of ski's for a beginner? I intend to go for twin-tips but width length and carve are a bit of a mystery. I'm 6' tall and quite weighty :D
Any help appreciated.
