>>1485610new wing is around 3 grand, used it's around 2.
a new airbag harness is about 700, you can get a good used one for half that.
vario, radio, helmet, etc can all vary greatly in price.
instruction also varies in price as it can depend on your rate of progression, weather, and your instructor.
I spent a grand for 3 days of quality instruction and I flew the first day.
I still keep in close contact with my instructor and ask him for advice often.
It's good to start building a relationship with pilots and they will start to invite you out to fly ins and events and you'll learn a lot in their company.
