First things first, air up your tires and put them underwater to see where the air is leaking - that will confirm/deny your assumption. If you can't get a tub big enough, mix some dishwashing liquid with water and put it in a spray bottle. Apply liberally and watch for bubbles.
It certainly wouldn't hurt to break the tires loose and examine the beads - if you lost a large piece of rubber you may need bead sealant, and that may not even work. Beads rarely get damaged the first time a tire is installed, but because they have seated, they routinely get damaged when they are removed from a wheel.
I would check the valve stems and install the sealant. I can't think of any reason why the tire sealant wouldn't help - it is distributed by centrifical force, but then it's the air pressure inside the tire that pushes it out anywhere there is a leak. If you want to examine the beads first do so, but I wouldn't ride anywhere without highlifter tire sealant or Slime installed. Even though I carry plugs and a pump with me, I don't carry a spare tire, and sooner or later, you're gonna have a problem on a trail where you'll be glad you installed the sealant.
