Well I think this should get you started. These and more can all be found on the home page of LRH. Have fun reading and don't be affraid to ask questions. Just try and be as specific as you can so that we can better assist you. Welcome to the addiction!
Just checking up to see if I have helped you out in any way. There is other stuff out there. If you go to Lilja barrels website, there are some great articles on their website with a ton of info on barrels, application, equipment.
Look up Demigod.com too. There are some here that don't agree with everything he has to say, but for the most part it is very informative.
