Yeah, you can just draw them using spritebatch :)
//HudTexture is a transparent texture the size of the window/screen, with hud drawn onto it.
SpriteBatch.Draw(HudTexture, Vector2.Zero, Color.White);
//Let's say that it works well to draw your score at [100,100].
SpriteBatch.DrawString(HudFont, Points.ToString(), new Vector2(100,100), Color.White);
if you plan on making more GUI (buttons etc) you might want to check out this answer I wrote to an other post: XNA DrawString() draws only a partial string
Also; For drawing scores etc, I have experienced quite a bit of boxing/unboxing because of ToString. For that reason, I have often had an array of strings to represent the score:
String[] ScoreText = new String[100000]; //As big as your max score
//In Initializing method:
for (int i = 0; i < ScoreText.Length; i++)
ScoreText[i] = i.ToString();
//In draw:
SpriteBatch.DrawString(HudFont, ScoreText[Points], new Vector2(100,100), Color.White);
