I have Under Pressure too, but I'll admit I've only tried a handful of items from it.
I occasionally will hunt down cooking temps, times and the like on the web. Also, I recommend becoming a fan of Sous Vide Supreme on Facebook, where they post quite a few recipes. Their website can also be helpful. And occasionally there will be recipes on Serious Eats too. I'm currently trying to perfect my fried chicken with my SVS and will post more once accomplished, but my guidance was really derived from various sources, all on the internet.
