When do you decide to proceed with cataract or glaucoma surgery in patients with non-quiescent herpetic stromal keratitis?   

Cataract surgery should wait until quiescent for at least 3 months. Glaucoma surgery, if emergent, may be unavoidable, but that has to be decided on a case-by-case basis.

I usually wait when they have been quiet for 3 months before proceeding with cataract surgery.

I try to do everything possible to "quiet" the eye before surgery. Sometimes, it is not possible, but that should be the goal.
