1. I don't wear Foundation everyday (I have sensitive skin) but I like Bobbi Brown's Foundation stick. I just dab it on my dark areas. Would love to try NARS next because I love their blushes but I'm going to head to their flagship store in NYC to color matched. Drugstore brand...I used to like Revlon but their Caramel shades have gotten iffy over the years. Also if you visit one of the higher end lines and find a color, check on Temptalia.com for a lower end match. She has a foundation matrix that's pretty spot on.
2. Try base coat and top coat. I like Seche Vite. You can find it at Sally Beauty Supply. I wear different brands of nail polish. Cheap polish ($1-$3), my favorite brands are Ruby Kiss and Soo. Drugstore, favorite brand is Sally Hansen. Over $8, favorites are Essie and Zoya. Zoya has a lot of special sales. Follow their facebook to catch them on a good deal. China Glaze is excellent also and Sally always has those on sale.
