Answer 1

you can use BackgroundWorker for that. There are plenty of samples that show just what you want to do.

Answer 2

See the System.Windows.Forms.ProgressBar class, and its associated example in the documentation. You'll likely end up using the BackgroundWorker component for this too. Here's an article with example usage.

Answer 3

ShFileOperation with FO_COPY and the FOF_SIMPLEPROGRESS flag.

You would need to use P/Invoke to do this.
