If you buzz on the mouthpiece alone, a strong sound with clear pitch should come out. The airstream will be easy to evaluate when you do this. Pitch can be learned, be patient, use a reference. Getting your mouth open requires strong muscles to control the operation.
To this list, I will add the tongue blocking the air stream. Keep in mind that in repose, the tongue almost completely fills the oral cavity. Arnold Jacobs called it an unruly beast. It can be relatively easily controlled by thinking of the low vowels, OH, OOH, and AHH. Say these vowels and then breath in and out while blowing on the back of your hand. You will feel just how thick the air stream is. Then, when you play, think of a voice that sounds like a tuba singing with those low vowel sounds.
In addition to buzzing easy tunes on the mouthpiece, also buzz whatever music you are playing on the tuba. Work on short phrases, and go back and forth between the mouthpiece alone and the tuba. The BERP is ideal for this because you can finger the valve combinations while you buzz. This provides a psychological stimulus that will help you get the correct pitch.
Allessandro Fossi has an excellent set of exercises for buzzing the mouthpiece that are complete with piano accompaniment, which will help you with the pitch. Take a look at his YouTube videos for a few examples. He uses flexible plastic tubing to add some resistance to the mouthpiece. The extra resistance also allows you to play slightly longer phrases than when buzzing on the mouthpiece alone. He also uses the Inspiron when buzzing, which allows the visual reinforcement of seeing the little ball being elevated due to the air stream. Personally, I use plastic tubing with a 1/2" inner diameter, cut to 4" in length for most applications. I use an 8" length in combination with the Inspiron. The longer tube also helps when working in the very low register.

If you want an example of great tuba sound, get the Brass Gym book by Sam Pilafian and Pat Sheridan. It includes a recording of those two playing every exercise in octaves.
