I actually have a similar problem in Paint7.
Which is why I switched to Paint.net. It sounds like your first problem with the magic selection tool selecting additional colors (such as colors very close to white) has to do with the tool's tolerance.
The closer that slider is to 100%, the more variations in colors it will select, while moving it closer to 0% reduces the number of shades to select. In this case, using a value under 10% will likely work well enough to ensure you select only the specifically white colors. From there, you can just delete the selected white pixels as usual.
After that, when you copy things in Paint.net with the rectangle selection tool, it will actually copy the actual transparent pixels as well, which is why it will similarly paste them over things just like with the rest of the selection. In order to avoid this, copy the object you need, create a new layer, then paste the object into the new layer. After you've positioned the object, you can then merge the layers back down again.
I hope this likely unnecessarily bloated text wall proves useful to you, and if you don't understand part of it, feel free to ask for clarification.
