I know several gurlies of that height who own and ride a monster, she should be fine with it!
As for the clutch, they are fairly heavy but a popular fix is to replace the slave cylinder with an aftermarket one, Spareshack supply them if you're stuck - problem solved.
You could always try the monster club,
