Lois & Clark never gave her a middle name but in the comics it's "Joanne". As for her birthday, in "Never on a Sunday" she tells Star she's a Libra and in "Tempus, Anyone" her AU grave gives her birthdate as 1967.
So anything between September 23rd and October 22nd of 1967 is acceptable.
"Let us remember that there is a creative force in this universe, working to pull down the gigantic mountains of evil, a power that is able to make a way out of no way and trasform dark yesterdays into bright tomorrows. Let us realize the arc of the moral universe is long, but it bends toward justice."
-- Martin Luther King Jr.
