I am not too familiar with the genre. Are there any good CDLCs available I should check out to help learn this style of playing?

Check out Creedence  Clearwater Revival CDLC's, Don Mclean, Elvis Presley, Queen - Crazy thing called love, and Steve Earl for starters.

 

Hears some sort of List From Wiki

I wouldn't have thought of CCR as Rockabilly. But I think I get where you're coming from.

 

I was thinking more things in the line of Wanda Jackson. I was surprised there wasn't more of this in the CDLCs...but that probably has to do with a lack of Guitar Pro Tabs to start with.

 

I know that there is a CDLC for Stray Cat Strut...  Search for anything else by Brian Setzer or the Stray Cats

There are CDLC for Summertime Blues and C'mon Everybody by Eddie Cochran.

 

Try Searching Gene Vincent, Carl Perkins, Buddy Holly, Link Wray, Robert Gordon, Jerry Lee Lewis.

Check out Prisoner of Society by The Living End.
