Sheep manure is supposed to be fantistic stuff! From what I have read it will not burn your plants and acts like a slow release fert.
As for the amount of peat I do think you can add too much. I would not go past equal amounts soil and peat. This is just my opinion. In seeding mixes that are mostly peat and vermiculite they add lime to balance the pH.
