2) because those tweaks come from fadefx's update zips, he is the gps expert. You flash his zip in a row with this one or merge them yourself, I'll add a link to his location: http://forum.xda-developers.com/show...postcount=8589. Actually I removed those tweaks for the same reason why I removed the gapps. I still use version 613 but most people prefer 828. You can flash the version you like, for example in a row with rommanager.
Besides that, I am spending my time more on learning how to build cm myself, pull commits, figure out git and github and I am working on an app that combines rommanager, nitrality and this zip.
