LATS hit it on the nose about the pickups...

As for the bridge... I'm not familiar with your specific model of guitar... however, I would do some more research... if you already haven't... into the Floyd Roses... particularly the Ibanez brand ones. They might be adapted to your guitar better than you think. The bad thing about htat is that it requires a lot of body routing. If you're looking to go from a hard tail bridge to any kind of tremolo... you better be ready to do a lot of routing and sanding... and test fiiting... and re-fitting... and routing... and sanding... and polishing... and so on. haha.
