Unless CustServ has ruled on it, the answer is "maybe". According to the glossary in the back of my 3.5 PHB, references to "allies" usually include yourself (oh so useful WotC should do a search for "usually" in 4e and re-write every instance so it can be removed). If forced to rule based on that, I'd go with you are your own ally unless specified otherwise.
WRT is broken. No amount of target finessing will fix it.
Leading the Charge includes yourself. WRT by strict reading probably does too, but really shouldn't.
Note: I base my interpretation of LtC not only on it saying all allies, but also because it's "Area: 60 ft emanation centered on you." To me, this sounds kinda exactly like a Marshal's auras--which he himself benefits from.
