Yeah, those are all good...it's just different ways that Windows displays file size. If you right-click..properties, you'll see 512,000,000 bytes for those 488mb ones.

For the 4.09m patch, try some of the various links here and see which ones work best for you:

I found the Myotherdrive ones fastest, but it depends where you are, etc.
I don't know of any torrents for the official patch, but maybe read through that whole thread and see if someone has made one.
