I think for 1- ayufan is the one to answer the question, but I believe 0.6.x pre-release images do not get automatic package upgrades, as for 2- config.txt is entirely RPi specific or even specific to your flavour of OS image you run. I prefer and promote using on-board linux mechanisms wherever possible - hardware configuration changes via devicetree (overlays) for example.
