If I could get 10K for that wand I'd be happy - most 5^50 wands seem to go for 3-5K, and I can't think of a build where there'd be a real difference between 8 and 9 fire.
+5^50 is max....but to me, it's better to have 20% recharge time (collector) wand than to have +5 energy. +Energy(wand) is not important for Elem when they have energy storage.
