Beauty: three questions in one skin, make up, eyebrows! ten points.?

Okay, sorry if this turns out long, i really didn't mean it too.

1) skin- I have not great skin but i don't have horrible skin at all, my acne is mild but I have a ton of black heads on my nose and underneath pimples under my skin around my lip area and my forehead. I have acene stuff from the doctor that I use, been using since april of 09. It actually cleared my skin up great, but like everyone I still have thoses problem areas. Is there anything that could help make my skin look better? I really don't use cover up. It never looks right on my face and I kind of think it doesn't help my acne really at all (like hiding it) any ideas?

2) Make up, What do you do with your eye make up? Do you change it up everyday or do you stay the same? I tend to stay the same with my eye makeup (I only used black eyeliner, a light eyeshadow and mascara) I can never really change my eye shadow up because I don't know what a good color would be for my eyes and such, my skin tone is like a light light olive, but I'm not going to get into detail really, how can I guess what eyeshadow would look good on me when I buy it in the stores? like what shade would be good, like how do you know?

and last,
3) I have dark dark eyebrows like almost black! I've been blonde since about may of this year, and realized I look best blonde, when I was going to my hair dressers in august I wanted them to color my eye brows because I think my eyebrows don't match my hair at all and they said no, if I color them they'll go orange? or something, so they told me to keep them thin, which I am but I'm sick of having such thin eyebrows, what do I do?

thanks for the advice then points best answer!
