For tournaments you can go to a few different web sites for tournament info depending on how far you want to travel. If you are just starting and your a mid level team you can look at rbsports.net or call 360-794-0655 and tell Rick that Ryan sent you.
You can also look at Oregon prep web site. If you search "oregon prep basketball" you will find the site.
As for uniforms, all you need is matching shirts with numbers.
If you want to scrimmage sometime let me know.
Good luck.
