I will note that George Lucas decided his cameo character (Baron Papanoida) was Pantoran rather than Wroonian after this episode aired.

Spoiler: An episode a couple seasons later

Baron Papanoida took over Cho's job, so I'm not entirely sure how monarchy-y (monarchish? monarchesque?) the whole thing is. Then again, baron is a noble title....And as you said earlier, "queen" is a title for an elected official elsewhere in the setting....
In conclusion, heck if I know; could be some sort of semi-presidential system for all I can tell.

Based solely on the name, I imagine repulsorlifts generate lift by repelling the solid ground below them, and "equal and opposite reaction" with the sheer mass differential means the repulsorlift floats relative to the virtually-unmoved planet, in apparent defiance of gravity.

C-3PO's whining at the beginning was to touch on this: Cho requested the Republic have an outpost there. Past that, I'd have to speculate to the point of making good-sounding guesses....
