What tools are required to replace a spoke? When out riding at the weekend, for the very first time, I managed to break a spoke on my wheel.

Because I've not done it before, and I want to get back out on the bike soon, this time around I am minded just to hand the job over to my LBS. However, I do like to do my own maintenance where I can, so was thinking about what tools I would need to be able to do the job myself in future.

I'm thinking I would need a spoke wrench, a truing stand and a spoke tension meter. But would I need anything else? Or are any of these items unnecessary?

As a follow on question, this was a spoke on the drive side of a rear wheel that was bought just 9 months ago as part of a new (and expensive) wheelset, and has done something like 1500km so far. The roads I was riding on were far from perfect, but I don't particularly remember hitting any potholes. Was I just unlucky or should I be concerned?

Update

I've now replaced the spoke myself with no hassle whatsoever. Thanks to all three respondents, every answer was good - a spoke wrench was the only tool required. I estimated the correct tension by plucking the spokes and made sure the wheel was approximately true just using the frame.

The only other thing to note was that, having decided to replace the spoke like-for-like, the particular spoke was very difficult to get hold of singly. In the end I ordered from an online shop in the US (I'm in the UK). I did approach my LBS but the best they could do was to order a box of 72 spokes for me which pushed the cost right up. I had a chat with the mechanic there who said that this was quite a common problem...
A spoke wrench is required, the stand and tension meter are optional but can make your job easier. You can use the frame of your bike and the brakes if you have rim brakes as your truing stand. If you have disc brakes you can use wire/zip ties wrapped around your frame tubes and poking toward the rim then trimmed to measure true (assuming the wheel is aligned in the frame.)

If you are replacing a spoke on a rear wheel you will likely need a lock ring remover and chain whip to remove the rear cassette.

Note that each time you break a spoke, the others become a little more fatigued, and a little more likely to break. Over time you may find yourself breaking spokes with more frequency. My rule of thumb is that if I've broken 5 spokes on a wheel I get it rebuilt, or at the very least professionally trued and tensioned.
