I store my 968 in a unheated garage in the winter. In late fall, I inflated all tires to 38 psi (+2 of the porsche recommend 36). Now that temparature has dropped to below freezing in the garage, the tire pressure is at 30-31. Should I inflat them back to 38 to avoid flat-spotting? If yes, do I need to deflat them when temp goes up?

Thanks

Sure, go ahead and re-inflate the tires, it certainly won't hurt. I don't think the tire pressures will increase much as temperature goes back up because tires gradually lose pressure, so these two factors may balance out. Even if the pressures went up to 45 psi it wouldn't hurt the tires unless pressure exceeds the maximum recommended value which can be read on the sidewalls of your tires. Just check the tire pressures again before you drive and adjust to the pressure you want.

^ + 1.
Put them in the high 40 psi range and simply bleed them down in spring after a few miles of driving to help get rid of the flat spots.

Put plywood under the wheels to keep the tires off the ground/concrete as well (or use something like Tire Cradles, etc)
