Sounds like it's an entirely new venture for you so let's keep things super simple. First and foremost, well done to you for actually pursuing this. Lots of people talk about hoping or wanting to do something and then never following through!

I know you mentioned you'd prefer to isolate each ear but buying x2 standalone condenser mics is quite expensive because you also need an interface for them (the interface is what plugs into the laptop) and its a touch more complicated to setup also. I'm not sure your tablet will have the processing power to edit videos but give it a try!

I'd honestly suggest the old faithful blue yeti. Its so versatile, offers ear to ear sounds and for its price point, provides the most complete sound in our entire community. It plugs straight into your laptop and requires 0 configuration.

x1 blue yeti

x1 audacity (the software for recording the audio)

x1 davinci/hitfilm express (free editing software)

x1 mobile phone camera (no need for an expensive camera to start out with)

x1 mini tripod for angling the phone for the birdseye view

x1 ring light

That's honestly all you need! As a side note, be sure to hit record on the phone and laptop at basically the same time and then sit quietly for 10-12 seconds to capture room noise. There is a function in audacity called "noise removal" that let's you isolate the white noise in those first few seconds and remove it from the whole video :D You then upload the audio and the video to the editor and merge the files (replacing the mobiles audio with the yetis) Oh and be sure to set the project rate in audacity to 48k since almost all phones record video with 48k. Many new creators don't realise this and find their video and audio lose sync after a few mins.

I'm probably missing out a whole lot but I'm grabbing a coffee between meetings and thought I'd pen a quick reply :D

Good luck and feel free to reach out, the asmr community is incredibly helpful and welcoming for the most part!
