It def helps to have an extra set of hands for sure, the hardest nut for sure is the upper ball joint since u can only get a wrench on it and not a socket, a cheater bar helps. Also from personal experience i wouldn't take anything off all the way just loosen everything it tells u to and its a lot easier, and yes go get it aligned afterwards to make sure the tie rods and everything are correct and tight (mine was off on one side for whatever reason).
