Looks like a basic loose balls/cup and cone, Square taper BB. You will need a wrench to fit the fixed cup, pin spanner for the adjustable cup and a lockring wrench for the adjustable cup lockring. A set like this would work but may be hard to find.

Your axle uses nuts instead of crank fixing screws - 14mm socket?
I can't say for sure if there are different kinds of UG freewheel removers. The Bikeman site indicates that one size fits all. The shapes of the remover and your freewheel look the same.
You would need a chainwhip to hold the freewheel in order to loosen it and a (large) wrench to turn the remover.
