Replying to Mid-life, beginner, East Coast and hooked on skiing. Help me pick my gear.

All it took was one trip to a local slope, next day I went gear shopping with the family. Finding gear for them was easier, for me not so much. First thing I did was get fitted for some boots. 3 hours later we had settled on Atomic Hawx Magna 100, only fit for my wide feet and robust calves. Can you please help me with the rest of my setup?

Main location: New England, East coast hardpack, icy, groomed
Beginner: But with quick potential and high desire to best my wife down the slopes
5' 9" about 230 pounds, thick build, was once athletic : )

Looking to get some skis, bindings and poles next although I was told not to use poles at this stage. Research so far is to buy some narrower skis for NE conditions, but with my height and weight would this be okay? I plan to buy from a local shop, but would love to get some thoughts so I have some knowledge before I approach sales people for their advice. For now I am renting skis as I continue to find the perfect purchase.
