Ah,
If you don't mind me asking which breeder did you get her from?
Has she pooped since you have had her?
You really shouldn't be handling them for the first week at least to give them time to settle into their new environment and feel secure. In fact if you can be strong enough it's best not to handle them too much until they are eating on a regular basis.
You temps seem fine ( maybe bump the hot end a couple of degrees but that's it ) though I would try and avoid any night time drop in general - though yours is small enough not to be a major problem.
The main thing though is to work out how and where you are reading those temps - not all thermometers were created equal.
If you want to put up pics and descriptions of the enclosure and equipment we could double check everything for you.
