May I see a few pics of him when you first got him? It will help me determine his age.. I am willing to bet he is older then they told you.
You will typically see a curbing down of food intake around the 9 month mark. This is your sign to take them down to every other day feedings, now with your boy I would take him to every other day 5 feeders. Because he is already holding excess weight. At one year for a male veiled your looking at every other day feeding of 3-5 feeders. Note for a cham that is holding more weight and is at the 1 year or older mark this would be further reduced to 2-3 feedings a week of 3 feeders.
Dragon ledges are awesome for attaching branches and pots. See this link.

@MissSkittles can post images of how she uses the plastic laddice in her cages for attaching things.
