tell application "System Events"
	tell dock preferences to set autohide menu bar to true
	tell dock preferences to set autohide to true
	do shell script "defaults write com.apple.finder CreateDesktop -bool FALSE;killall Finder"
end tell

Since your code is only for hiding, you can make it toggle with a single script like this:

tell application "System Events"
	tell dock preferences
		if ( (autohide of (get properties)) = true and (autohide menu bar of (get properties)) = true ) then
			set autohide menu bar to false
			set autohide to false
			do shell script "defaults write com.apple.finder CreateDesktop -bool TRUE;killall Finder"
		else
			set autohide menu bar to true
			set autohide to true
			do shell script "defaults write com.apple.finder CreateDesktop -bool FALSE;killall Finder"	
		end if
	end tell
end tell
