PBS Space Time - How Much Information is in the Universe? link It is a finite number and it's a big number, but still finite (and proven). link Also the playlist Understanding the Holographic Universe from PBS Space Time ▶ this video and Entropy Explained! link
Your description of hawking radiation isn't quite accurate. It's a popular misconception. the actual process is not as easy to understand. see below: ▶ this video That said, what the OP said about "borrowing" electrons I am not sure about.
man, watch the PBS YouTube channel SpaceTime. They're short, informative, and very well done. they dedicate a handful of episodes to getting you ready for Hawking radiation. ▶ this video
The particle-antiparticle explanation is just an analogy and doesn't really cover what actually happens. I thought this video from PBS Space Time explains it really well while keeping it accessible for non-physicists: ▶ this video
There's lots of different ways to approach explaining the phenomenon of hawking radiation, PBS space time does a good job here: ▶ this video Ultimately, hawking radiation does not come from within the event horizon, so it can escape into the wider universe.
