I'm kind of confused, is it 300mm * 1.4 = 420mm X 1.6 (10D)=672mm or is it 300mm * 1.4 + 1.6 = 900mm (doesn't seem right) Help us newbies, I'm sure others have this questions in mind.

It is 672mm. A 300 mm lens with a x 1.6 crop factor = 480 mm. Add a 1.4 TC to that, you get 672 mm. There are a lot of old threads here about both the 1.6 crop factors, and teleconverters, if you're interested. 1D Mark II and stuff
