If you use mineral foundation I'd definitely recommend Fix +. I noticed a HUGE difference when I started using it, and it sort of makes me wonder how I functioned without it.
I love MAC cheek color. Blush doesn't stay on my face well, even with Fix +, and MAC stays the best.
I second the nomination of Vanilla pigment. I use it on my cheeks as highlighter, brow highlighter, over eyeshadow to lighten the color...I use it on a daily basis.
I'd also recommend a few eyeshadows. I'd speak with an MA about what colors would go best with your eye color/complexion. I'm NC 15/20 (read: pale) with dark hair and dark eyes, so I love darker colors. For every eye color I like Satin Taupe, Vanilla (it's different than the pigment), and Woodwinked. I like using Nehru (similar to Carbon) and Plumage (a deep turquoise/black) as eyeliner/outer V contrast. I also am in love with Sumptuous Olive, which is a gold/green. Depending on the light, it can look more green or gold.
I hope this helps. There are a lot of fantastic MAC products, and honestly, if you choose something different, it's not a bad choice
