A few questions about wisdom teeth extraction....?

It's been three days since I've got my wisdom teeth removed and I've been wondering when should I brush my teeth again, I have been using warm saltwater to rinse my mouth but my teeth just look horrible. I was thinking about later in the day. The swelling in my face has gone down some but it's still sore. I was wondering what should I do to get rid of the soreness and also wondering when would it be safe to eat hot liquids, and when it's safe to eat crunchy food like nachos or foods like pizza. Also when would be the best time to eat spicy food? Also when can I start laying down again without blood coming out?
