what you have there looks good to me
couple things to consider...
what kind of yeast are you going to use?
what temperature do you think you will be fermenting at?
most wheats are pretty light on the hop bitter and aroma so you may want to adjust the Hallertau addition to go closer to a specific style if that is what you are going for.
you will get some additional sugar out of the limes for priming so I would stick to the standard 4 ounces of priming sugar instead of upping to 4.5 to 5 oz. which is common with wheats.
EDIT: I would also recommend skipping secondary, and leaving in primary for 2 weeks
