You can also try covering the rack or blacking out the sides of her tub. I've had good results using this trick with fresh imports or stubborn hatchlings. As far as cluttering the tub up, you want it so she can't really move without touching something, even if its just crumpled paper or fake plants. I've also found it helpful to make the bedding really deep so there's less of a gap between the bedding and the top of the tub (for some reason I've had the best luck using cypress mulch for this).

As far as switching to F/T goes, my experience (I fed F/T until we started breeding feeders) was that it was easier to get them eating consistently and then make the switch. BPs can be shy eaters, but they also seem to need some movement from the prey to eat. So the problem with starting with F/T is that you have to be standing there to make the prey move.
