What is the death and injury rate for 'accidental' firearms injuries? Pretty darned low: The CDC reported 613 'unintentional' deaths from firearms in the US in 2007 (the last year figures are reported).
http://webappa.cdc.gov/sasweb/ncipc/mortrate10_sy.html - plug in various causes, etc and see for yourself.
The vast majority of firearms deaths are caused by criminal activity, either criminal on criminal (the largest group), criminal on victim, or law enforcement involvement (some half of all-cause firearms deaths are by law enforcement shootings).
As far as your claim that training will help, it doesn't seem to. As I said earlier extensive training and licensure is required to drive a vehicle in the US, the similar death statistic is 43,945. In fact, there were more deaths of bicyclists (820) than accidental firearms deaths.
Neither driving a motor vehicle or riding a bicycle is a right. However, defending yourself from attack is a human right, a civil right, and a right that the Constitution guarantees (although it is a natural, God-given, right).
It's apparent that depending on law enforcement to protect one from criminals is a fools bet. In fact, the DC Court of Appeals (the second most important court in the US) found in Warren v. DC, it is a "fundamental principle of American law that a government and its agents are under no general duty to provide public services, such as police protection, to any individual citizen."
http://scholar.google.com/scholar_case?case=9108468254125174344&hl=en&as_sdt=2&as_vis=1&oi=scholarr Read about that case, where the DC police were told of the attack these women were going through, and for 14 hours did nothing - legally.
So, to be able to protect themselves from a criminal (and as you claim anyone can be a criminal) something to equalize the disparity of strength and force needs to be done - or the victims remain victims. Firearms provide that equalization of force. As the saying goes, "God created all men, Col. Colt made them equal".
You continue to advocate for a required safety course, using the argument that it has to be a good idea...... Yet, it provides a simple method for a government to prohibit firearms ownership for everyone simply by not making such 'approved' courses available. Hawaii used to have such a policy (the course was offered once a year by the state police, in Honolulu, and class size was very limited). Here is a link to the current law in Hawaii
http://www.capitol.hawaii.gov/hrscurrent/Vol03_Ch0121-0200D/hrs0134/HRS_0134-0002.htm, it wouldn't take much of a change in the law (delete all of paragraph g except g2, and then don't offer the classes) to prohibit lawful ownership. In fact, Chicago is doing that now, effectively: Their application form requires a class from a state-licensed instructor and that the instructors license number be entered on the form. One problem: The licenses don't have a number....but the police will take your money and keep it, and after 6 months or more reject your application as being incomplete.

The Second Amendment Foundation and attorney Alan Gura (the winners in the Heller and McDonald cases) are now going after both New York and N. Carolina
http://saf.org/viewpr-new.asp?id=331 for their arbitrary requirements to exercise your rights - which can easily be manipulated by unscrupulous civil authorities to deny those rights to you (as happened here, as well:

If you want to advocate for firearms safety classes, great. Become a firearms safety instructor and offer lots of classes. Mandating the classes as a condition of exercising your human/civil/Constitutional rights is a threat to those rights you say you support. After all, all genocides in the 20th century started out with victim disarmament, all done legally and in the name of safety or civic order:
