I think the main for running a basketball team is organization. I can not tell you how many times I have seen other coaches have players just standing around doing nothing.

I am a big believer on not a minute being wasted in practice. Organize practices so that every player is doing something to improve themselves. Example: If you have five doing defensive sets. Have the rest work on passing drills on the other half.

Another thing is you must believe in what you're telling your players because if you don't they will know.

Here is a sample practice format I used for kids in your age group.

5 - Warm Ups (Stretching, Sit Ups, Step Slides)
10 - Suicides
5 - Lay Ups
5 - Suicides
5 - Layups
5 - Suicides
5 - Water Break
15 - Defensive Drills/Set on the other court passing/shooting drills
5 - Step Slides with Passing
15 - Rebounding, Passing, Fast Break
15 - Scrimmage
Losing team has to run suicides while winning team has to make 10 free throws.

Add some variations but this is just the basic format.

I do want to add that individual stuff is going to be hard to do without an assistant or two. So if you have one then you can break them down in by group (Guards, Bigs) and teach them group specific stuff.
