Yeah, I think "send all the relevant reading materials before hand" is great, and I'd add "and make sure everyone reads them" which is a cultural thing.

Another great one is to differentiate between items which are 'for decision' and those that are 'for discussion' - it sets expectations. If something is 'for decision' then the max-4-sides reading materials should cover all aspects (pros/cons) and it should be possible to make a decision from the materials.

If something is 'for discussion' then the meeting is going to contribute to the reading materials so there will be missing parts, or perhaps controversies that need to be hammered out in the meeting.
