Quick questions - Pre-ordering from the Paradox Web Shop

[mib]

The available information seems scattered and confusing, so I'm asking here to get a definitive answer, hopefully.

If I pre-order the (boxed) game from the web shop, will it...

1) Have the various pre-order bonuses?
2) Have Steam integration?
3) Require Steam integration?

Steam (although I'm no sure about absolute requirement), no DLC.
