3.) Only use Frostbomb when you have 2 FoF up. Any other time is a waste of a GCD and leads to an overall loss. That being said you should always cast Frostbomb on PC since they have the same duration; then try to generate as much FoF as possible.
4.) You shouldn't need to, since you no longer need to line up your FoF generating CDs with PC. Just pop them with Icy Veins in order to extend with FoF ice lances. They should all be back by the time Icy Veins comes of CD.
