I had to correct your spelling since it bugged me so much.

As for a distance, I would say try to focus it for at least 50 feet or more. If you can get a tiny dot at 50 feet, then you'll have a better divergence than most lasers do to begin with. Plus, there aren't many applications you'll need to use your laser for where you need a really tight dot at 50 feet except for showing off with match lights, balloon pops and so on.

Basically you shine the laser at wall that is at least 30 feet away and adjust the laser until you get the smallest possible dot. Although it takes a lot of trial and error it really isn't hard at all.

one thing that helps when collimating, is to have it on a wall or something pretty far away. and have a friend down looking at the dot telling you whether to keep turning the lens or if the dot is good. That's how I collimated some of my lasers. It works pretty well!

In my experience the mirror will enlarge the dot artificially and make it seem larger than it is.

As small as possible. Go for the best divergence that you can get.

Dime at 25 feets sounds good to me. That actually beats a couple of my lasers.
