What skin care stuff do I need?

My father-in-law gave me some money for Christmas to spend only on myself (I spend all of my money of my 2 kids normally). I currently use normal soap and hand lotion on my face and I know I'm not supposed to. But when I went to the beauty section of Walmart, I got really overwhelmed. I didn't realize that there was so much stuff…. Please help, I have "combination" type skin (oily except for my forehead, chin and nose). I'm also starting to show my age…
