Yeah, I change my jewelry everyday (almost). As long as they're healed!! I'm with ya...I like to wear my earskins a lot because I like how the hole looks, but I have to wear solid plugs to work.
The only thing I've ever heard about acrylic is that it shouldn't be worn in fresh/non-healed/irritated piercings. Acrylic is very porous (spelling?), meaning that it's full of tiny holes that can trap bacteria. Since acrylic can't be autoclaved, there's no way to clean all that bacteria out of those little holes...so if you have a non-healed piercing, that bacteria can cause your piercing to get infected.
I, too, love white plugs! If you like white, but don't want acrylic, you could try glass colorfronts or Kaos solidfronts. I actually have the Kaos ones in white, and I wear them all the time. They're superbright white. However, I've heard that silicone (Kaos) shouldn't be worn in fresh piercings either? Someone correct me if I'm wrong.
