Lift done correctly will not ride any worse than stock. Fix the problems and enjoy the higher ride height
As far as getting it back to stock height, if it still has stock uppers/ lowers, or if it has adjustable LCAs and UCAs you're pretty much looking at swapping in stock coils, and doing a re-alignment. If it also has aftermarket front and/or rear trackbar(s), they may not be of correct length or cannot be adjusted short enough. Getting it back to stock really depends on what is already installed.
