For progressBar: Use a System.Windows.Timer class. You only have to get the total time and then set the beginning and the end of the timer. Use Tick event of the timer, to move the progressBar forward.
Heres an example:

private void InitializeMyTimer()
        {
            // Set the interval for the timer.
            time.Interval = 1000;
            // Connect the Tick event of the timer to its event handler.
            time.Tick += new EventHandler(IncreaseProgressBar);
            // Start the timer.
            time.Start();
        }

        //The following codes will make the progressbar increase the step one per time.

        void IncreaseProgressBar(Object sender, EventArgs e)
        {

            // Increment the value of the ProgressBar a value of one each time.
            progressBar1.Increment(1);

            if (progressBar1.Value == progressBar1.Maximum)
                // Stop the timer.
                time.Stop();
        }

About the playList. You have to get the files from specified directory and show only their Name.
Use a FileInto[] array to get and use them to play.

DirectoryInfo taskDirectory = new DirectoryInfo("specify full path to the directory with mp3 files");
FileInfo[] taskFiles = taskDirectory.GetFiles("*.mp3");
