Lots of details to address, but the short answer to your question is the pro's use armaflex on every pipe above frost line. I don't see why the pool noodles wouldn't work, as they are closed cell also.

Yes, the pipes will interfere with each other if you lay them close eough together. Whether that will make a difference depends on lots more details.

As always, proper preparation prevents poor performance. Keep on with the planning and asking questions. There are many successful DIY geothermal builders just waiting for you to get interesting.
