I don't know if it's in the OCR formula booklet, but in Edexcel there's a list of things which integrate to inverse trig functions. This is one of those.
3. Not sure how OCR differs to Edexcel. The Edexcel formula book has a standard result for this type of question in it. The method would be to factorise u^2-1 and then write the whole expression in terms of partial fractions then integrate from there.
