Answering your cycling questions

If your three piece cranks have a 19mm spindle, then yes.
If they have a 22mm spindle, then they will need the 22mm Mid BB.

The KL40 has a Mid BB so the bearings will fit, but whether you need a 19 or 22mm depends on the size of your crank spindle, you need to find this out first.

Yes but you wouldnt need the 19mm version not the 22mm.

This is a BMX Only bottom bracket as it is for frames with a mid size bottom bracket shell.

I'm not familiar with the Verde range, myself, but the following info will help you out:
The important measurement in terms of your bike is the fact that this is a Mid-sized BB, as opposed to a US- or Euro-sized one.
If the frame accepts a Mid BB, then any Mid BBwill fit.
Your BB axle for your crankset will be either 19mm or 22mm, that's what makes the difference in sizing here.
