Well, you're most likely going to have to change your WiFi card. If it's an Intel card, will not work. Some Broadcom cards work. I would take a look at this article for the card that are known to work.
For sound, use VoodooHDA. It's the easiest way to get sound to work.
AMD (or even NVIDIA) graphics, since this is a laptop, won't work. Since the laptop switches between Intel graphics and the dedicated card (to save power), Hackintosh doesn't support that. So, you'll be stuck with Intel graphics. In Clover, go to options --> Graphics Injection, make sure "Inject ATI" is off, and that "Inject Intel" is on. If you're still having issues, let me know. I'll need the model number of the laptop.
