Answer 1

If you don't mind using GUI Scripting, and provided Safari is already open, the following script should do the trick:
set downloadsPath to "/POSIX/path/of/destination/folder"
tell application "Safari" to activate
tell application "System Events" to tell process "Safari"
    click menu item "Preferences…" of menu 1 of menu bar item "Safari" of menu bar 1
    click button "General" of toolbar 1 of window 1
    tell window "General"
        click pop up button 5 of group 1 of group 1 -- "Save downloaded files to:"
        key code 125 -- down arrow
        keystroke return -- "Other…"
        keystroke downloadsPath & return
        delay 1
        tell sheet 1
            if exists static text "The folder can’t be found." of sheet 1 then
                display dialog "This folder can't be found:" & return & downloadsPath buttons {"OK"} default button 1 with icon 1 giving up after 10
                click button "Cancel" of sheet 1
                click button "Cancel"
            else
                click button "Select"
            end if
        end tell
        click button 1 -- close the window
    end tell
end tell
Tested under OS X 10.9 “Mavericks” with version 7.0 (9537.71) of Safari.
