I don't know about colorado law / licensing process, so I won't comment on that.
I highly encourage you to get your CHL. If you're not comfortable carrying yet, don't do so. But having your CHL is a great thing in case your situation changes and you make an enemy. Get it, get more comfortable with your gun, and have it in case you need to carry sooner than later. My wife has an ex boyfriend that I'm always on the look out for.
Regarding accuracy -- get good. Practice hitting your target every time. But realize that if you're in an actual gun fight, there's a good chance you're going to miss the bad guy with some of your shots. That happens all the time. Minimize that possibility as much as you can and pray you never have to use your gun in a defensive situation.
Your experiences with LEOs will vary. They're individuals with opinions just like anybody else. I've had both positive and negative reactions from cops when they find out I carry.
If nothing else, it's a vote of sorts -- it's one more person in the state of colorado who feels like it's his right to carry if he so chooses. It gives the politicians something to think about.
