#3> It may be time to upgrade your garage door opener.
If you're worried about this, make sure your garage door can't be opened with a coat hanger as well:

Also most of your door locks can probably be opened in a few seconds with the right tools+experience:

Of course someone could always just throw a brick through a window.

#4Which should I consider more insecure: my garage door, or the deadbolt on my front door? I wonder how commonly lock picking is used in crimes. I've picked a lock before myself, but I have no real idea how effective locks are in stopping people that want to commit house thefts.
I expect an automated garage door opener is much easier to use than a lock pick though, and probably easier to produce and distribute than lock picks. So I shouldn't consider garages as secure.

Criminals use lock picks when you don't want someone to know that they broke in. Most criminals are the "snatch-and-grab" type. They are more likely to look for an unlocked window or just break a window.
Oh, and deadbolts are pretty easy to pick.

#6The "De Bruijn sequence". I was wondering what that was called, since I realized it's optimal for creating IFS fractals. I figured it must have a name. Yay!

My parents did the thing where they put keyed deadbolts on all of the doors. So when someone wanted to break in they broke the glass on the door, discovered the deadbolt, broke the glass on another door and discovered the deadbolt, then broke the glass on a third door before yet again being foiled by the deadbolt. Then they broke a window and stole our stuff anyway. Apparently they were professional thieves too, since they were hitting half a dozen houses each day while driving through the state. The cops finally caught them when they were pulled over for driving on expired tags or something stupid. They had robbed over 100 homes in two weeks before they were caught.
The only thing the deadbolts did was to make us replace three extra windows.

Exactly like computer security, it's not about making it impossible to gain entrance[1], it's about making it both inconvenient enough and require enough skill that it takes longer or is more noticeable, making it more likely the intruder will be noticed, thus raising the likelihood they will be caught.
That said, a few seconds is a pretty low bar. Commodity locks should be better than this, for all our sakes.
1: This applies to anything where someone has access. It's trivial to come up with ways to secure things that need no ingress/egress whatsoever.

They're also frequently banned by fire codes because you can't get out of the house without the key. Blocking egress paths is a no-no.

The counter-coat-hanger-ziptie method is great, and I use it. But for the sake of safety, I recommend a thin ziptie - something that would break under the weight of an adult. It's still plenty strong enough to prevent the door being un-coupled by a coat hanger, but weak enough that an adult (inside the garage) could make an emergency exit.
