I always find all those Generals to be a good thing for her to level with--she had two of her personal tomes at that point for me, along with Tauroneo with Imbue, so I actually got her to about level 14 after her promotion, for one reason or another >.>
Yeah, if she has Paragon and you pretty much use up her Prf you'll be fine as far as Micaiah goes, she'll be a decent level by the end.
