First couple of uses had me stumped too but with practise it all came good. Only real tips I could offer would be fill the jug to just below the base of the spout and position steam wand straight down about 1cm off the wall of the jug. Lower the jug until you hit the sweet spot and the torroid gets going. I am lucky with the length of the steam arm on the BDB in that it allows me to simply rest the jug on the drip tray and start the steaming. I slowly raise/angle slightly the steam arm and then let go of it to position cups and start the shot. Oh, and I did also find that putting milk in the jug and placing it in the fridge for a few minutes did provide for much more froth - something I am not a fan of but the wife and mother in-law enjoy a lot. Hope that helps in some way...
