For your tree frogs, it's really a matter of preference. Lobsters can climb, so maybe that would be more appetizing to the frogs, but turkistans are softer bodied and higher in protein, but can't climb. Also turks are egg layers, so your setup would have to be a bit different.
As for the beardie, a small colony of those "discoids" they have would work nicely, although it would take about 6 months to get fully established, whereas a massive colony of lobsters would do good as well.
