Sephora also carries Bare Escentuals and will also do free makeovers for you.
I wear BE. I wear fairly light, but I haven't tried their matte collection. I also wear some liquid foundation, but that is more rarely. I always wear the same foundation color, unless I get more of a tan in the summer - then I switch to light and add bronzer if necessary. Foundation should be chosen based on your skin tone, not what you are wearing!
I hardly ever wear eyeliner - I wear eyeshadow in a neutral color or two, or a color complimenting my outfit. I always use mascara if I'm wearing eyeshadow.
If I decide to wear makeup, my "everyday" look is Makeup Forever concealer, BE foundation, Urban Decay eyeshadow in X, and some mascara. Sometimes I use a pressed powder foundation if I'm in a hurry or skip the eyeshadow, but if I wear foundation I always put on at least a little bit of mascara.
More elaborate makeup for me includes more eyeshadow colors, eyeliner, and blush.
