About to post my setup. For the switches I just set it up in target so that both the up and down switches send a pulse for the toggle. This isn't ideal but so long as I make sure the switch is in the down position before I start the game (I usually log out in a station) then I just have to flick it up for gear up and back down to lower again. Same goes for the scoop but I start the game with the switch up and then can flick it down in the game to lower the scoop.
Would actually be nice if FD could add separate gear up and gear down commands to map to the switches though. There's probably a way to do this in TARGET but I'm not a pro used by any stretch.
It would be simple for them to just add another toggle yes/no setting to the gear and scoop in a similar fashion to the toggle or not toggle choice on the reverse throttle mode and flight assist. That way the switches on the Warthog would work.
