Acer Iconia Tab A500 - Rooting & Honeycomb 3.2

I just bought a brand new Iconia Tab A500. I just unboxed it and it shall be charging for the next 14 hours :) While I wait for first booting it, I have a question on rooting with 3.2. The tablet comes with Honey 3.0, but I read that the 3.2 update is ready to be delivered OTA. But I absolutely want to root it! 1. Can I root the device after the OS upgrade? 2. Or should I root it first? 3. Or, does upgrade remove rooting and currently there's no [yet] rooting for HC3.2? Thank you
