I would buy brushes if you don't already have a decent set.
Carbon eye shadow is fab for smoky eyes and Style Snob colour is supposed to be very on trend this season. Ask for them to tell you what colours they think would work for you, you can never too many MAC eye shadows!
Barestudy paint pot eye shadow is the best eye base in the world!!! Grey Utility eyeshade, MAC Red, Lustering, Darkside, Bombshell, Ruby Woo, Girl About Town, Cockney Lipsticks. Sharks Skin Shade stick. Peachy keen blush, gives a lovely warm glow. Eye pencil in any colour. You could stock up on black and grey eye pencils and clear lip glass and give then to aunts, nieces, cousins as Christmas gifts.
