Two mouths on one body — how do I keep the pair routing from crossing underneath?

Bring each port's pairs straight back from its own tails and let the two groups run parallel rather than crossing. The mouths are far enough apart that there is room, provided you do not try to share a via field. If the board is tight, escape the inner port first, then fit the outer one's pairs around it.

The table still lists a one to one turns ratio — what does that mean with no magnetics fitted?

It describes the module we recommend for this jack, not something inside the shell. Because the part is a passive connector, the ratio column is there so a reader can pick a matching transformer without hunting through another document. Confirm the recommended module with the drawing before you commit the land pattern for it.

The shield has no EMI tabs — how do I get a chassis connection?

Through the solder tails and the board ground, or through a separate finger gasket that touches the plate. Without tabs the shell relies on the tails, so give them a solid plated pad and plenty of copper rather than a thin trace. If the enclosure is metal and the seam matters, add the gasket and check continuity from shell to chassis.

There are no magnetics inside — what has to sit on my board instead?

A discrete transformer module per port, plus the termination network the PHY expects. Place each module close to its mouth so the pair length between jack and winding stays short, and treat that link as part of the differential path. Two ports mean two modules; sharing one across both mouths will cost you crosstalk and a layout headache.
