I'll appreciate your grammatical corrections for this passage. Thanks.
However, with ignoring the gap between vision and reality, the president could indulge in talking about future reality of a prosperous, blooming and especially - democratic region while avoiding any mention of the difficulties and the challenges which the region is confronted with. The president even went as far as harnessing the ruler of… to the wagon of change and progress, imploring him gently to generate change in his country, as though the ruler of … is part of the solution rather than the source of the problem...
My second question: How do I know when to use/ not to use the article (a) before nouns such as future, change, part etc.?
You can say "ignoring the gap" without the by, but that is asking the reader to ignore the gap. If you say "by ignoring the gap", you are saying the president was the one doing the ignoring.
Here is a good article on using articles ;)

I said "a future reality" because you are saying there are many possible futures, but one of them involves prosperity. I really think articles are one of the hardest things to master when learning English. It is funny, because native speakers don't even have to think twice when using articles - it just sounds right or it doesn't, but it is hard to come up with rules or reasons.
