Yes, good question! "Including" is either a preposition or a verb. As a preposition, "including" means "such as." Example: "the store has many different fruits, including pears, apples, and grapes." As a verb, "including" is the active present form of "to include." Example: "I am including my mom in my wedding ceremony." "Inclusive" is an adjective that means "containing a variety of items" or "not excluding things." Examples: "The US is moving away from discrimination to create a more inclusive society." or "The price of the vacation was inclusive of food, drinks, accommodations, and activities."

Looks good to me, but I have one main edit: Instead of "or former asperger syndrome" I would say something like "formerly known as Asperger's syndrome." It gets capitalized, and "former" is an adjective whereas "formerly" is an adverb describing the verb of knowing the title of the disorder. Or, if you want to emphasize that now ASD is an all-encompassing term including Asperger's, you could say "This article aims to clarify the importance of school inclusion in the teaching of English Language (LI) for students with autism spectrum disorder (ASD), which is an all-encompassing diagnosis that includes what was formerly known as Asperger's syndrome."

Hi! "Whenever" is used more for repeating events, whereas using "when" would imply a single event. i.e. "whenever I drive, I blast music." (implies you drive regularly) vs "when I turn 25, I want to have a party." (it is a single, non repeating event-- you can only turn 25 once) So I would say, "When we can no longer download for free, we will feel dissatisfied." or, for something more informal, "When we cannot download for free anymore, we will be dissatisfied." "anymore" and "no longer" mean the same thing, but "anymore" is more informal.
