Sorry for the annoyances, this is my first game and I just want to make sure I am on the right path.
Yes that's right. I tend to keep my game loop fairly simple, it will call two functions, the first called Process() (or Update()) that handles the movement / AI / Game States etc, and another function called Paint() that deals exclusively with drawing the game (you don't want to do processing update within your draw loop). In this system the Draw function would simple get the position of the paddles and the ball, and draw them at that location. The process loop would update the position and speed values, and check for collision.

Having never used Dark GDK I can't really say, but a pong clone shouldn't take you long at all (an experienced game programmer could make it in under an hour). If you're experimenting with things though and learning the system, then the time doesn't matter, providing you learn from it (in this case it would only improve your performance at future DarkGDK projects).

Give the AI a maximum paddle speed. and only have it move when the ball has passed a certain point (eg. past the centre of the play area). You may also want to increase the ball speed each time the player or AI hit it. That way you can make the ai quite accurate at first, but as the ball speeds up and has more lateral velocity (forcing the AI move more), the AI will struggle to keep up. This gives the player a good challenge, and allows you to tweak the difficulty level easily too. Other behaviors for the AI could be to always follow the balls position, or to move back to the centre when the ball is traveling away from it.

More than likely 'no'. If you make it into something like what my version is intended to be like (3d/cool graphics, particle systems, power-ups, perhaps multi-player, unique game mechanics) then yes it could go on your portfolio, but if it's a straight pong clone, it's not even worth mentioning (like I said above, anyone reading your portfolio could probably get the same result in an hours work).
