As you said everything is on hiatus for the moment (but not necessarily due to GZ case) Mostly due to some legislative slight of hand.
Generally speaking we do have Castle Doctrine in Nebraska in as we are not required to retreat from our homes, now extending that to car, business, anyplace you have a right to be- (essentially SYG) hasn't really went anywhere.
Now the Civil Liability Protection- aka Victim Protection Act- is the biggie that the NFOA was trying for, In a nutshell the bill got neutered.
I believe it is on the agenda to go after all this again, but first we must work ( thru the NFOA-PAC) to get the soon to be (term limit) vacated seats especially those on the Judicial Committee, filled with pro gun, common sense legislators.
AAllen had a nice write up elsewhere here on this all recently, but for the life of me I can not find it.
