I'm very pleased with [Autrelle Holland's Aiki-jo manual,][1] which contains the Suburi and Kihon (I believe those are what you refer to as "small kata". 
I've also been impressed with [Stanford Aikido's discussion of the Jo Suburi][2], which contains some very precise, practical advice and a wonderful sense of humor.  

Of course for video the Saito Aiki-Ken and Aiki-Jo disks are excellent - although one of these days I need to get around to asking why Saito-sensei breaks his wrists at the end of the stroke and why he drops the sword behind his back at the beginning of the stroke.
