Rated 10/100 for monitoring and smart meters - how many pairs are used?

This jack is specified for 10/100 Base-T on 2 pairs of the 8P8C set. The bridge taps the remaining conductors for the supply path on this model. 802.3af is the quoted standard. Your meter design and the 802.3af budget close that allocation.

EMI tabs with a tab down latch - what does the panel cutout need?

Spring tabs run along the shell edge while the latch hangs below the opening. A coated upper band and a folded lower lip each remove one needed clearance. Spring tabs run along the shell. The masking callout and your cutout drawing define both strips.

Green and yellow LEDs on a 10/100 jack - where is the current set?

The lens leads exit as bare pins with the bridge occupying the diode position. A series resistor on the host board limits current once the rail is chosen. The lens pair is green and yellow. Your GPIO assignment and the lens forward voltage fix that value.

A rectifier bridge is fitted - what does that change at the supply pins?

The LPJ4190-8GENL places a bridge ahead of the centre tap pins on the data pairs. Polarity on the incoming feed becomes less critical at that stage of the circuit. The bridge sits after the coil taps. Your PSE wiring and the 802.3af schematic settle the rest.
