I like the light to come from above and, as I have the same problem you see to have (meaning, the ceiling fixture not been directly or even close to been above the cages), I solved it by putting a hook (like this one:

Please be careful which 'regular' fruits and veggies you feed her. Parrots are all undomesticated species (well, with the single exception of the English Budgie) and have no resistance whatsoever to bad chemicals so, in my personal opinion, they should not be fed any of the ones on the 'dirtiest list' (strawberries are the worst). Here is the list for your information (they put out a list every year:
https://www.ewg.org/foodnews/).
You are free-feeding the protein source food and, contrary to what the breeder told you (breeders are really not the best source of information on pet birds), this is not really recommended. Birds need protein for life and breeding and, because the sources of plentiful, high protein are VERY rare in nature, they are hard-wired to crave it and gorge on it when they find it so, if you free-feed protein food, they will eat too much of it and too little of the 'healthier' food (produce, whole grains). I feed mine the healthiest food in the morning for breakfast and all day picking and the protein at night (because, in the winter, the nights are very long and, as the body takes longer to digest protein than it does produce, they feel full longer). I don't feed pellets because, after doing research on parrots diets for over 20 years, I still haven't found anything about them that tells me they are the best dietary option for them.
I would also not take the bird out until she feels 100% comfortable in your house and trusts you implicitly - unfamiliar and open spaces mean danger to a parrot (read high stress), especially if it's all by its lonesome (the flock provides the security there is in numbers). Your bird is only now beginning to get over plucking and, if I were you, I would do my outmost to keep as much stress as possible from her life (stress creates anxiety and that's why they pluck).
