The problem with requests like this, historylearner, is that while we'd LOVE to tell you what we think, we are really constrained not to help you with coursework, because the exam regulations state that it must be your own work.
Certainly, you MUST cite any help you get here in the credits/bibliography at the end of your essay.
And, whereas teachers might well help you clear up any final details/ questions you might have, I suspect you will find that no one is prepared just to wade in and give you advice on the original questions, as you have posted up here.
Sorry if this seems mean, and best of luck with your essays.
In the meantime, why don;t go go and chat with your teacher, who
IS able to give you reasonable help and advice, such as he would give any pupil.
I think I can tell you that there are web-based materials on Northern Ireland at:
