The last post is correct, in that typical bookshelf, indeed most other decent or semi-decent 'speakers, will be fine.
The previous statement "If you have an amp that is rated at 50W RMS, then you need speakers rated much more than that, as there will be peaks that will exceed 50W." is not correct.
No music will drive an amplifier to its continuously rated average power (which is what is meant by "r.m.s.").
In fact, the average power from any music signal will be significantly lower than the maximum continuous rating so there is no point whatsoever in using 'speakers with a higher rating.
The peak of the average continuous power is twice that (average) figure, and will be of such a short duration that it will not harm the 'speakers.
The 'peak music power' is a figure for a non-repetitive peak and will be even more than that, but again, since it is by definition non-repetitive, it constitutes no danger for the 'speakers.

Most of the above answers are correct. It's usually not the "watts" that ruin speakers, it's when the amp distorts or "clips" that ruin speakers. Make sure the amp can drive the impedence of the speakers. An amp only rated for 8 ohm loads will burn up trying to drive 4 ohm speakers. Luckily, most of the 4 ohm speakers are usually foreign or high end, so I don't think you will run into that problem. Definitely the higher the efficiency of the speakers will get the most of your amp without straining it. As with all stereo equipment, stats don't really mean anything, they are a loose guide. Listen to what you want to buy first.

50 watts isn't that much, especially if it's peak power instead of RMS, like the first guy said. In that case, you'll want to get as efficient a speaker as you can. Efficiency in a speaker is the amount of sound it will put out for a given input at a certain distance. This is usually a sound pressure level (dB or decibels) at 1 watt from a distance of 1 meter.
The reason you want highly efficient speakers is that it takes a lot less power to drive them at a certain volume. This leaves you lots of extra power - called overhead - to handle transient bursts of sound without causing the amplifier to clip. Clipping of an amplifier is when the amplifier is overdriven and no longer produces a smooth sinusoidal wave. Instead, the tops and bottoms of the wave are "clipped" off, resulting in extreme audio distortion. A power amplifier that is clipping can also cause voice coils in speakers to burn out, even if the speaker power handling rating is higher than the amplifier's rated output.
The most efficient speakers I have seen are Klipsch. But, the good ones can be expensive. Here is a link to an eBay listing for Klipsch KG .5 bookshelf speakers that I think you would really like:

These speakers are small (about a foot high), but they put out great sound with just a little power input. I bought a used pair of these a couple years ago on eBay and I think they came out to about $60, plus $20 shipping. Which isn't bad, considering they retail for over $200 a pair. I use them with a Klipsch powered subwoofer and they sound great. But, even without the subwoofer, you'll be impressed with the sound. Very loud and clear, and surprisingly good bass for such a small speaker.

Power rating on both amplifiers and speakers isn't actually that important you basically can mix and match as you like.
Where power comes into play is when you have difficult to drive speakers (speakers with a low impedance, or with a low sensitivity). Before you get to the end of the power your amp can produce or your speaker can take without overloading, the sound will long be way to horribly distorted to listen to.
A typical bookshelf speaker should do fine on your amplifier.

You will also have an Ohms rating.. usually 8 for a hifi, 4 for a car stereo..
Also bear in mind the watts are measured differently in cheap systems.. they express "peak music power" which is 4 time the standard "RMS" which is the proper rating..
If you have an amp that is rated at 50W RMS, then you need speakers rated much more than that, as there will be peaks that will exceed 50W.
I would suggest at least 75W speakers, rated at the same ohms as your amp, and preferably 100W or more
I also advise that you get to listen to a few pairs before buying, as it will save disappointment later..
