Looks like time well spent.
The conditions Incognito has suggested are good. Although I don't know much about child custody cases, here in Australia we have a system where problems and issues are sorted out through an intermediary system first, in an attempt to avoid costly court battles.
If if you are to place conditions on your partner then they will generally not be accepted or seen as reasonable unless you agree to abid by the same restrictions yourself.
How would your partner feel if you were to take her to non JW religious activities? Often churches provide an after school story and play time once a week. It can be fun for the children but you may be totally against this idea yourself. It is also the wrong thing to do if you just intend to do this as a retaliation.
