Looks like everything has been pretty well covered. I did want to add one thing regarding the a/c though. Your bird will be fine with any temperature you are comfortable at. Drafts are one thing to be aware of though with the a/c. Where you keep her cage should be completely draft free. A draft can easily make you bird sick. Also be careful of any fans, ceiling fans or otherwise. Never have a fan blowing on your cockatiel and be sure she is never getting a draft from a fan. Also of corse never have a fan on while your bird is out of her cage. Some birds can still fly even if their wings are clipped and a fan can be deadly.

Congratulations on your newest addition.
