congratulations on your new baby girl
the only thing id advise is, dont wasten your money on expensive toys for her... sure get her a few cat tree's ( you can get them off ebay) but mine love to play with screwed up paper balls, they play with them for hours.. and drinks straws.. they love to play with them too..
she will settle down after a few days but if you keep a few litter trays around close by she wont be too stressed and will use them straight away as long as they have the familiar litter in..
also if you give hand fed treats several times a day and 'click' your fingers when you shout her name then she will love you all the more and learn to come when called
