Use what works well. question 5: I'll usually put bootstrap into its own folder, have a style.less outside of the folder that imports bootstrap.less, import stylesheets with custom mixins after bootstrap.less, and import straight up custom styles after that. question 6: go into bootstrap.less and comment out the stuff you're not using.
