for RandR I use ARandR for a gui, or just used commands, or use my openbox menu items and hot keys I created, for my most common usage, which is to mostly to rotate the screen. There is also Drandr for use with dmenu, and urandr and xrandr guis.
I use blueman or commands for bluetooth. Also have some openbox menu items I created for some connections.
For networking I use netcfg with profiles for main networks and wifi-select for random wireless connects. There are guis for netcfg also but I don't use them.
