It's been a long time, hasn't it? Can you believe it's been almost a year since the last one?
The girl is Cyclone from DC Direct. Riker's console is actually the Enterprise NX-01's tactical station, which is why he's mentioning Trip: Charles "Trip" Tucker III, the ship's chief engineer. As for why Riker's there, Enterprise's final episode was revealed as a holodeck recreation Riker was running during TNG. That's the justification, anyway; the plain reason is it's the only DS/AA Trek-scale console available, and there's no such thing as a bad DS/AA Trek figure.
It's good work too - part of a four-part build-a-bridge - shame the market didn't support it due to Enterprise sucking so much. If you weren't collecting at the time, don't worry: this tac console (which came with Malcolm, the not-gay weapons officer/Trip's hetero life-partner) came from a back shelf in a forgotten toy shop years later, so if you want one, you can probably find one if you really look.
