Nice to hear from you again.
If your income during Ausbildung is not sufficient to pay for a living you can apply for BAföG or BAB ("Berufsausbildungsbeihilfe"). You are eligible for it after staying in Germany for 15 months (or longer) without interruption (with Aufenthaltsgestattung and/or Duldung).
Usually it is not possible to get Wohngeld during Ausbildung. You can only apply for it if you are not eligible for BAföG or BAB.
