I just kegged/tapped my first beer recently. I got some great help and tips from my local home brew store.

Are there any good books or websites out there that get into the specifics of kegging for home brewers?

I know a lot of books just touch on it briefly, but I am looking for something that goes into a little deeper regarding balance of the system, maintenance/cleansing, bottling kegged beer for competitions, etc.

Sorry, no book ideas. But as far as bottling from a keg...

I had an IPA I brewed with a friend I only see rarely and after kegging and carbonating I bottled some using the "Beer Gun (tm)". It works wonderfully, but you lose a little carbonation. I shared the bottles several months afterwords and they were great, but less carbonated. I think if you were looking at competition, I'd carb them a little higher than you want and then bottle them. And expect a few days of checking/tweaking if you're really anal about your carb level.

As far as maintenance, I rinse my tubes regularly with sanitizer solution, but replace them often since they're so cheap.

You can bottle with a rubber stopper, picnic faucet, and a short tube. Its the stuff like for refrigerator cold water but bigger. It fits in a picnic faucet. You put it through the stopper that fits in the bottle and turn the faucet on. It will build pressure in the bottle. Once the filling slows way down you just let a little bit of air out by letting the stopper up a bit. You can work it so it slowly fills and does not foam at all. Stays carbed pretty good too. Plus its way cheap!
If you have questions just ask.
I soak my kegs with oxyclean. Then i flush them out really good.

There are a few references available for draft.

I've just got 2 major criteria that brewers should follow:

1) The temperature from keg to faucet should be constant.
2) The resistance of the dispense line should be 1lb less than the dispense presssure.

Most references are made for commercial systems, but the concepts are universal.
