The Man with the Twisted Lip
The Adventure of the Blue Carbuncle
The Adventure of the Speckled Band
The Adventure of the Engineer's Thumb

From what I can tell from a quick internet search, Volume 1 of this audiobook covers the Holmes cannon faithfully from the first. I'm eager to start Volume 2 to see if the coverage will be as comprehensive.
I liked Charlton Griffin's Sherlock and Dr. Watson, but I didn't like his portrayal of any of the female characters (they sounded so wimpy and foolish, even when they were written otherwise).
I read several of the short stories, out of order, years ago. Listening to this audiobook to "read" the cannon from start to finish is great because I can follow the character development of Homles and Watson, and their relationship.
...and this is my favorite store on the Internet!
John Grey, a seemingly minor character encountered by the main protagonists of Diana Gabaldon's Outlander series, becomes a central character on his own in a series of short stories and books. He is a soldier, a gentleman, a noble man (in the original sense of the word), a sodomite, and an altogether human hero - often dragged into the heart of 18th century intrigues during the time surrounding the 7 Years War (French and Indian War to the Americans) in the years between the Scottish Jacobite Rising of 1745 and the American Revolution in 1776.
Readers of this series might give the Outlander series a miss, but you will lose out on serveral interactions between John and the Frasers that give a richer view of the character. The Outlander novels are a whopping 40 hours each on average, where LJ reads range between 1 and 14 hours.
You should definitely not read the Lord John series out of sequence to itself, which is easy to do accidentally since chronologically it alternates between shortstories and full length novels. Hand of the Devils contains three of the four current short stories, and while they are in order in this collection, make references to events in Private Matter and Brotherhood which leave the reader wanting to know what the heck happened though it does not have an immediate impact on the story.
As of October 2010, the order to read Lord John in is:
Hellfire (Hand of Devils); Private Matter (novel); Succubus (Hand of Devils); Brotherhood of the Blade(novel); Haunted Soldier (Hand of Devils); Custom of the Army (Warriors, Anthology); Scottish Prisoner (novel not yet released).
