This may help. One little-known feature: if you drag a folder to a File Open/Save dialog, it'll navigate to that folder! (This is unlike Windows, where it would move that folder.)

If you have the folder already open in another Finder window, you can drag its icon next to the title in the titlebar (top of window.)

You can also drag a folder (or that icon) to Terminal to grab the path.
