A couple thoughts.
1. Way to go in deciding to take the plunge on going pro. Let us know where you are planning on setting up, as a couple of us are certainly within driving distance.
2. Make sure you are planning your brewing capacity such that it will support your project for the next few years. If you are going into this seriously, you should have goals for how much you want to produce in 2010 and how much in 2011 and maybe 2012. Make sure the purchases you take at start-up can support it. Last thing you want to do is have to re-buy equipment because it turns out that a 1 barrel system won't cut it. But also, make sure you are realistic and don’t swing for the fences.
3. All the pricing in your post reflects brand-new equipment. I would highly suggest you be vigilant and look into used equipment. Keep your eyes open for old brewpub equipment etc. With this economy, there is a lot of equipment out there you can pick up on the cheap which will be higher capacity than you could probably be able to purchase new. Just be smart and research the hell out of any piece you might be considering - there are great deals out there, but you have to look under the chassis to make sure the deal isn't a lemon. Make sure to surf through
http://www.probrewer.com and other resources.
4. Make your local connections now (if you already haven't). There is a tremendous 'buy-local' movement that will be your low hanging fruit in the beginning. You need to make sure you get that early revenue - but more importantly the reoccurring revenue. Everyone will try something new once, but your job will be to make sure they come back for a second, third, etc.
Lastly, here is an amusing article if you need a little fuel for the fire.
