Limb wood is gonna go all crazy not matter what you do. If you leave it whole, it will part where you don't want it to sometimes, sometimes cleanly along the tension/compression line. Aside from reducing and using a caul it's a crap shoot. I'd at least part the stuff 4" or bigger once.
A couple of good coats of shellac is the best and most cost effective sealer I'm told, and if you haven't had problems using glue you've been lucky.
I personally leave the bark on and have had very good luck cutting wood before the last frost, getting it reduced to say 4" to 6" quarters before the warm temps come. If I was gonna cut this year, I'd of been at today or already done. Last chance for frost for us is about April 1. I think the bugs are after the sap, if you give the wood several months to dry before they hatch you greatly reduce the chances they'll infest the wood. I"m going on 6 seasons or more with no bug damage, but my first few were horrible.
Also, keep wet white woods segregated. I generally don't cut it, and generally debark it immediately, but have had BIG infestations if the bark is left on.
