several of the things explicitly mentioned here are supported not only by most gun-owning citizens, but even by most NRA members...
Let's look at the poll questions you linked to:
1. Requiring criminal background checks on gun owners and gun shop employees. 87 percent of non-NRA gun-owners and 74 percent of NRA gun owners support the former, and 80 percent and 79 percent, respectively, endorse the latter.
2. Prohibiting terrorist watch list members from acquiring guns. Support ranges from 80 percent among non-NRA gun-owners to 71 percent among NRA members.
3. Mandating that gun-owners tell the police when their gun is stolen. 71 percent non-NRA gun-owners support this measure, as do 64 percent of NRA members.
4. Concealed carry permits should only be restricted to individuals who have completed a safety training course and are 21 and older. 84 percent of non-NRA and 74 percent of NRA member gun-owners support the safety training restriction, and the numbers are 74 percent and 63 percent for the age restriction.
5. Concealed carry permits shouldn’t be given to perpetrators of violent misdemeanors or individuals arrested for domestic violence. The NRA/non-NRA gun-owner split on these issues is 81 percent and 75 percent in favor of the violent misdemeanors provision and 78 percent/68 percent in favor of the domestic violence restriction.
Nothing in there about mandatory training for possession, any form of registration voluntary or otherwise, no ownership or ballistic database, in other words NOTHING TO DO WITH WHAT YOU PROPOSED IN THE FIRST PLACE. Never mind that it was sponsered by an extreme anti-gun lobby group in response to the NRA promoting a law that required all states with concealed carry to honor those issued by other states or opposing legislation that would allow the government to declare any gun owner a terrorist and immediately arrest them for owning a gun (the entire reason why question #2 on that list exists.)

There's a significant difference between requiring a safety class to participate in a heavily regulated activity such as hunting, and requiring a safety class to own something. The average person has ready access to plenty of things that have just as great (if not more) potential for accident as a gun, but we don't see people advocating for requiring liscences for ownership of space heaters, automobiles (liscences are required only to drive on public streets, simply owning the vehicle or driving it on private property does not require one), alcohol, or power tools, despite all three causing as much destruction due to recklessness as any gun. (For that matter, cars may eclipse firearms in suicides (this is impossible to determine, because an unknown percentage of automobile suicides involve driving the vehicle into an obstacle at very high speeds, which is rarely distinguishable from an accident unless they leave a note).)
