Be brave man! Like I said, second brew down and I have already had a crack at steeping grain, adding hops to the boil, making a hop tea etc, it all seems daunting at the start, but just get your head around a few basic concepts and you'll be wondering what the hell you're gonna do with all your kits when you've decided that you're moving to all grain brewing anyway! (Or is that just me?)
All the stuff you need to make a Stone & Wood-ish copy should be available from a decent homebrew store, or just get it from one of the online stores. The process is all pretty straight forward, I will be putting one down very soon! (Just finishing my last S&W for the evening now...sadness)
While the AG guys talk about wheat and malt and grain ratios and all that stuff, you can do that on a simpler, lower level by getting a can of light malt extract and a can of Coopers Wheat or wheat extract (just cans of goo) so once you break it down you realise just how easy it can be. If you start with a nice, low bitter, light malt base, you can allow the hops to do all the talking. After all, S&W pacific is a nice, light coloured, low bitter ale with a massive smack of passionfruit from the Galaxy hops. Give Lord Raja's recipe a go and see what you think, thats the way I'll probably be going as well.
My advice is read as much as you can here, disregard the instructions that come with the kits regarding fermenting temps and think about investing in some decent yeast for starters. Brew at around 18 for an ale and you should avoid a lot of the esters from kit yeast (brew too high and it makes your beer taste like cheap cask wine, well, it did for me anyway) or get onto a nice clean ale yeast like Safale US-05.
I've brewed one horrible beer, and one that tastes like awesome REAL beer, and I have this forum to thank for it (and pennywise who I harrassed via pm)!!!
Be brave man, be brave!!!
