   I don't think there is any need to do that. I assume your resaw cut will be close to the eventual planed surface. Shouldn't be enough to matter.

   I normally face joint one face and use it against the fence when I resaw. If the board is not flat to start with, then you have multiple not flat boards after you resaw.
   When possible, I resaw a test piece of the lumber I am going to resaw, to see if both pieces cup immediately toward the blade. If that is the case, you will probably be ruining lumber by resawing unless you have an abundance of thickness. You will have to wait for the moisture content of the inside and outside to stabilize, and for internal stresses to ease.

   As always, it depends...

   If the wood is properly dry then it will almost certainly do all its moving when you cut it.
   If cutting multiple slices, I joint between passes though it's rare I'll cut more than 3 pieces from a chunk of timber, and for that I just joint both sides.

   It never does any harm to wait a while. I try to do milling before lunch or dinner, then leave the part milled wood whilst I eat - if it has moved any during the meal I'll have a long think about whether to use it or do something else.

   I'm with rob_ss, it depends. Nice Q-sawn stock tends to resaw flat, smiley-ended boards often turn frowny. Cutting a sample chunk is a good idea if you have enough. I wait a day before continuing unless I'm cutting veneer.

   I did a nice simple test based on your comment and am happy to report that it came out just as expected. Q-sawn stock trumps again.

   As a hobby woodworker, I have time. I've seen enough things move when I resaw where I'd prefer to wait.

   The conventional wisdom is to re-saw slightly thicker than your planned final dimension and then let the pieces sit at least over night, preferably for a day or 2. Then mill to final dimensions. Re-sawing wood releases a bunch of tension in the wood. As the tension releases, the wood will move. If you mill to final dimension right away and start building, you may run into problems as the wood moves.

   And sticker or let the pieces stand upright so air circulates around them. I try to mill my boards 16th thicker and at least 1 inch longer than needed. I also try and allow 1/4-3/8 wider. But resawing does release stress in boards so you may have to abandon some. Always mill more than you need to account for this. Also means you have test pieces ready.
