I agree with the bare minerals make up. I am doing my sisters make up in April for her wedding. I did read somewhere not to wear any pink as it does not look good in photos.
I am planning on using bare escentuals foundation, bronzer and finishing powder as a base. Then a mixture of brown eye shadows, a light beige for whole eye, then a pale brown over most of crease and then a dark in outer corners and brown eyeliner. A gloss most likely for the lips.
As for clearing up skin, I use proactive solution but would not recommend trying a whole new regime 2 weeks before your wedding, some make your skin worse before better. Maybe get a spot treatment containing benzyl peroxide (only use a small amount).
Good luck for your wedding
