Good suggestions. I'd also make sure that you buy a tubing cutter, which will ensure that the cuts you make are nice and square. Don't try and do it with scissors, or a flush cutter.

Also, just make sure that the fittings are pressed all the way down. Some people don't get them all the way in. Unlike a lot of other connectors, they seat under pressure, which means that if they're leaking, you can lean down on them, and they should stop.
