Also: I'm seeing from various websites that the maximum time-left-to-serve for minimum security (federal prison camp) is 10 years, but nothing definitive - [1] is the most in-depth but only specifies this requirement for male prisoners, whereas other requirements are clearly distinguished between male and female.

Generally, yes.
If her sentence is high she might not classify as minimum security (prison camp) and might have to serve some years at a medium before being moved.
Remember, federal prison sentences are generally "85%" which means you can get 15% off your sentence for good behavior. Almost every prisoner will get the maximum 15%.
I didn't read the indictment. Are her offenses nonprobationable? Usually non-violent offenses are probationable for first-time offenders.
They're actually even more specific for fraud cases, beyond the general 2B1.1 basic economic crime rule of sentencing according to the most severe count; for fraud, you apparently sum up all the losses from all the counts, which has the net effect of bumping Holmes up 2 additional levels.
