Two For The Seesaw by William Gibson is a great 2-hander, that was made into a film with Robert Mitchum and Shirley Maclaine, and later the musical Seesaw. It is about time it had a revival.
The 2-hander show I Do, I Do, with music by Harvey Schmidlt, was a musical version of the 2-hander play The Fourposter.
For monologues you could try some of the Alan Bennett plays from his Talking Heads series.
I didn't get to see David Hare's The Breath Of Life with Maggie Smith and Judi Dench, but I seem to remember reading that it had a cast of just the two of them.
