Here is a link to many Canon products in PDF form: Canon Parts Lists
Unfortunately, the only 300mm 2.8 lens listed is the IS version
The procedure is not that complicated, but you need to pay attention to the connections on the circuit board. The mount is removed, and you need to remove the small screws that hold the connector board to the mount ring first.
I cannot do live chat due to I use a Mac, but I will monitor the thread if you have questions,

Your question ( in laymans terms) is unclear! But I will make a guess as to what it is you ask.
The 100-400mm is the focal length of the lens, To use it it has to be attached to the camera It it is capable of focusing clearly on an object at its maximum output as well as its minimum. At its maximum focus it can perhaps ( depending on optical quality) bring an object 4-5 Kilometers into clear view. Most lenses have a zoom factor and a focus ring. Experimentation with the lens will be a better way of defining what improvements it has over a standard 50mm lens

Is the lens tension adjusting ring too tight? Try loosening it and see if you get increased travel. If so, you may need to have it checked out.
