Crogati : Did I understand the logic and the elimination process correctly?

I believe you did, but you just left out negations for the last two terms: No keyboarding skills -> -use computer -> -Use word processor
"no" needs to be added to computer use and word processor use, it's a small detail but thats what the lsat is about, details.

This is question is a great example of inferences making tested both in logical reasoning and in analytical reasoning. You want or should see the inference that links "no keyboarding skills" ---> no word processor use. Thus, the contrapositive tells us that "word processor use" --> keyboarding skills.
