If you haven't already got the supplements can I suggest you get pure calcium and Repashy Calcium Plus (available from Lilly Exotics) instead. Nutrobal is ok but the Repashy supplement is far superior.
You can use the pure calcium (no D3) for dusting insects (although it doesn't adhere to the bugs very well) and in a bowl inside the viv for them to self supplement. You can add supplement to the mealworm bowl if you wish.
I think I've seen people favour lino over repti-carpet on here. I personally use repti-carpet, never had a problem with it so I highly recommend it. Either of those are fine though
