The last Kent dual drive I messed with came with a Falcon Freewheel. They look to be close to the Shimano removal tool but the Shimano tool you listed won't quite work.
Servicing the hubs is a good idea but why are you messing with the bottom brackets? My GUESS is they are sealed units - they don't get serviced, just replaced once worn out. And I'd consider is quite an accomplishment to wear them out because these tandems are not bike shop quality and have caused a lot of frustration just trying to keep them working (shifting, braking) properly.
On the cones for the axles-
The "manf" may have substituted a different axle/cone assembly from year to year, so there's no guarantee that you need the exact size cone wrench somebody else used.
IF you can post pics of the BB assembly, the "rest" of us can advise what tools to use for that. The manf could have substituted there too.
Many times they buy their parts from the lowest bidder!
The Falcon & Shimano FW tool seem to be somewhat interchangeable, but if you have a Falcon FW, get the Falcon tool. (FR-7)
