In the device settings you should be able to swtich from asio4all to your audio interface (it will probably be called behringer usb or something like that) if you installed the driver for your audio interface. This is how I would do it in FL Studio.
I looked at a tutorial to see how you’re supposed to do it in Reaper because it’s different for each daw and here’s how you should do it: press ctl+p to open “preferences”, then you click on “device”, then under “Audio system” you shold choose “ASIO” and then the “ASIO Driver” should appear right under it and there you should find your audio interface. If your behringer interface isn’t there then you probably don’t have the driver installed so you should quit reaper and install the driver. Then you set up the inputs and the outputs and that’s it.
After that you should connect your speakers to your interface but honestly I don’t know how you would do that with bluetooth speakers because you have to connect the speakers with cables to your outputs on the interface. If you have some speakers that aren’t bluetooth try connecting them.
After you did all that you should be able to normally record and listen to any audio without a problem.
A condenser mic can do a good job with recording drums but the problem is that the drums aren’t recorded with one microphone. They are usually recorded with at least 8 mics. There’s a mic for kick in, kick out, snare top, snare bottom, tom 1, overhead left, overhead right, room. You could try to record the “room” with your mic but the “room” mics are usually just blended in with the rest of the drums and it most likely won’t sound very well.
I don’t have experience with recording electronic drums so I can’t really help you with that. But I know how to program drums with VSTs. If you can’t figure out how to record your electronic drums you can download “MT Power Drumkit 2” which is a free drum VST that actually sounds pretty decent and program the drums in your daw.
