if you know how to do the burning, you can do any and all of the tasks you mention- with the reservation that you can't 'play' a CD of midis the same way you'd play a regular CD, and not in a portable device. You can choose a list of midis from Windows Media Player and play them in order. (Atleast I assume you can...I use Media Player Classic, which I like MUCH better, and it will play 'almost' anything. I just played 4 midis in a row using it. There are many wonderful free programs which will play MP3s, and MP3s can now be played in many portable devices, too...
