No worries squiddo! Would you believe short term memory loss is a side effect of our hobby? 
I'm not sure the DE will do anything for your pest management in the soil mix. I used to work for a pest control company and we only used DE in dry areas as it tends to loose it's killing prowess when wet. People put DE in mixes to supply silica, an essential plant micro nutrient. As far as water I prefer to use RO water, that way I get to choose every component that goes into it, no guessing what's already there. I prefer it to distilled, but have no good reason why. Remember, even if it starts at ph 6.3 you're going to have to adjust it to 6.5 after adding nutes, or to water with it plain.
