If the air bubbles are relatively small, poke or drill a hole through the cloth and fill them with epoxy. A small syringe works well; my Pygmy kit came with 2 of them, but I don't know where to find them at a store. If your epoxy is still green from the glassing job, you may even be able to squeeze the bubbles down a bit so there's less of a lump.

The whitish areas I am guessing are foamy epoxy. I have this only in the stem and stern of my kayak where I have a big enough epoxy fillet that any loss of strength of is inconsequential. Strength-wise you're probably O.K. here as long as you can't depress it with your finger. Another possibility is that the whitish spots are where hot-melt glue used to be if you used it to tack your forms to the panels. The hot-melt seals the surface of the wood and doesn't allow the epoxy to penetrate.
