I'm trying to recreate the movie trailer for ESB in fullHD. So I looked through the trailers from the official 2004 DVD and found a TV-Spot that had the space/explosion/Vader helmet without the title on it. So I need to resize it to 1920 x 1080 and then crop it to 1920 x 816. I know, it would not look as sharp as the rest of the trailer, but I am trying to get the best out of the sources I have.

I also want to color-correct it, so the space is really black again and the stars are white (or almost white). And all that without loosing the details of Vader's helmet. There's also a lot of noise in it.

What software do you recommend for the color-correction, denoising and enhancement? Is that even possible? Are there any tutorials? Anyone else how did something like that (upscaling a dvd movie to fullHD?) and has some hints for me?

Here's a pic of the scene I'm talking about:
