For 4) most dev-boards I worked with uses "As Input-Tristated" or same with week pull for configuration. You can select this in the device settings. You should look into the manual of your board, because when there are other components connected to the FPGA you are not using right now there is the possibility to shortcut things with "output to gnd". Input-Tristated is most times more safe for the components around, but must not be everytime like that.
