Which tee "connector" should I buy to install this one?

It's hard to know which tee you need without knowing pipe and pipe size, but the 1804 heads have a 1/2" Female insert pipe thread if that helps.

Can I make this go only 6', with 90 degree angle or with 180 degree angle??

You can reduce the flow and pressure with the set pin on top, but it would be tough to get down to 6 feet on most irrigation systems (assuming good flow and pressure 40 to 80 psi). The head can be adjusted to any angle from 0 to 360 degrees and in any direction. You would be better off to get the 1804's without the 15van nozzles and order 8van or 6van nozzles to go on them separately.

No, these are the standard non-pressure regulating heads.

When I adjusted the screw on top, it disappeared into the body and won't back out; water sprays straight up. Can anyone offer a solution?

With the water off, take the nozzle off of the top of the head. If there is a screen in below the nozzle, you may be lucky and the screw will be sitting in the screen. Just re-attach it to the underside of the nozzle. If you cannot find the screw, you will need to replace the nozzle.
