EffectsLab does not contain any keying filters. Maybe you're getting confused with CompositeLab?
What is the difference between a bluescreen and greenscreen other than the color?
Nothing, they perform the same function. The reason you might want access to both is so that you can cope with blue and green subjects.
Some digital cameras also work better with greenscreens, so if it doesn't matter what colour screen you use, I'd recommend going with green.
Hitfilm: Is Hitfilm easy to use?
That will vary for every individual user, but we've certainly done everything we can to make it as easy to use as possible. There are also lots of video tutorials to help you learn: http://hitfilm.com/video-tutorials/
Does it support 1080p quality?
Does it support sound unlike effectslab and Dolby Digital Audio?
HitFilm does include sound support. We're currently finalising some licensing issues regarding Dolby audio.
Without a particle system, can you do weather and fantasy/magic scenes in Hitfilm standard?
Some weather effects are included with HitFilm Standard. As for 'fantasy/magic scenes', you would need to be more specific.
How do you edit the sky in Hitfilm like in the demonstration video? How do you create a backdrop for the greenscreen/bluescreen?
Backgrounds can be anything you want - image, video, or something created in-program.
As Biblmac says, the best thing to do is try the demo and watch some video tutorials.
