Keep cool, Bat Goddess baby!

Hey, I now have herbs in many pots, any advice for particular pruning style and frequency for, alphabetically:

Basil: I hear snip at the two-leaf level to get it to split there like a hydra, but how often?
Lavender?
Oregano?
Parsley, curly and flat?
Rosemary? Very woody, what should I use if my scissors aren't happy?
Thyme?

I also have some hot peppers and cherry tomatoes... am having fun, never done this before.
