Changing your water parameters over time

In doing my research on switching over to a SA Cichlid (Bolivian Rams or GBR) tank as well as maintaining a nicely planted tank I came across a question about water. So my regular tap water has a pH of 8.4 a GH of 300ppm and KH of 300ppm. Now what I did is in my treated and standing water (that sits under my bed in a 31L plastic container) that is going to be used for water changes and evap, I mixed 1G Distilled water with 4G of tap water. The Distilled numbers read as follows 6.2 pH, 0GH/KH (they both read zero). When I combined the water I got a very nice reading of 7.2 pH, 150ppm GH, and 180ppm KH. Are those numbers more sustainable for Rams? I also spoke to the LFS and there water that they have their rams at is sitting at 7.8. With those two pieces of driftwood, how much will it lower my pH? I am going to slowly change my pH and GH/KH down with my current fish for a month or two and see if I can sustain these numbers.
