Yup, that's a lot of stuff, but your browser can usually do most of the work for you. If you hover over the title for a post and then right click, some browsers (like FireFox) will pop up a menu. The menu should have an option something like "Copy Link Location" which will copy the full address to the invisible "clip board". Then you can paste it where you want it with "Control-V".
