Welcome Graeme.
Your brewing skills will come in mighty handy for whisky making.
I would recommend going with a modular pot still so you can expand to a bubbler at a later date should you so desire. If you're not terribly handy, or lack the metalworking tools required, check out some of what 5 Star have to offer - the 4" pot still (
http://www.5stardistilling.net/4-modular-pot-still) is built like a tank and will last you a lifetime. As for a boiler, you can either go for a modified keg that but will require some metalwork before you can use it or you can look at something like a ready to go milk can boiler such as this (
http://www.5stardistilling.net/50l-milk-can-boiler/).
Ignore the "out of stock" messages on the 5 star site, it rarely reflects the actual availability of any items. If you are interested, it's best to contact them to discuss your needs.
As for books, check out the distillers library here (
http://aussiedistiller.com.au/viewforum.php?f=47) and also read all of the threads in the newbies section. Twice. Therein lies most of what you need to know. :handgestures-thumbupleft:
