When I was there in January I rented Rosignol E-88s to demo from Beaver Creek Sports. I loved the skis! Beaver Creek wanted $800 for the while they were available online for $600. Beaver Creek Sports matched the online price and gave me credit for my two days rental. So don't be afraid to ask for a price match.
Concerning lift tickets, I saved by ordering online a week prior to arrival. Be sure to join Vail's Peaks Rewards program as it is essentially a 10% rebate. It is good at Beaver Creek, Breck, Keystone, Canyons, Heavenly, Northstar and Kirkwood and Vail.
