Questions from inexperienced dom

Im now in a situation where I can explore my dom side a bit more as a man with a woman who's submissive. Ive not explored this side in much detail at all but I was hoping you guys could give me few tips.

She likes rough sex and is into spanking choking hairpulling dirty talk etc. For choking and hairpulling what is the correct technique for maximum pleasure? And any general tips anyone would like to share would be appreciated im very excited to try things out.
