Actually it's 300 Watts.
"Handles up to 300 watts peak power and 75 watts RMS (continuous) power @ 8 ohms"

Since that amp is slightly under powered for those speakers & have quite a bit of Total Harmonic Distortion (0.08% THD @ 8 ohms) you are at a slight risk of damaging your speakers with that amplifier. But it's actually a pretty close speaker/amplifier match up so you need not worry.
Ideally an amplifier's RMS wattage per channel (at the speaker's Oms rating) should be 1.5 to 2 times higher than the speaker's RMS wattage. The amplifier should have a THD rating of 0.05% THD @ 20 Hz - 20 KHz or less. Avoid any amplifier that has a THD rating of 0.1% THD @ 20 Hz - 20 KHz or higher.
Since your Klipsch RB-51 bookshelf speakers are rated 75 watts RMS @ 8 Ohms the ideal amplifier for them should be rated between 112.5 Watts RMS per channel @ 8 Ohms & 150 Watts RMS per channel @ 8 Ohms with a THD of less than 0.05% THD @ 20 Hz - 20 KHz (8 Ohms).
The difference between 100 Watts RMS & 112.5 Watts RMS is extremely minuscule.
You should never turn the volume knob of a receiver (or an Amplifier's preamplifier) past half way up. This is so you don't risk clipping the signal to your speaker & you don't risk your amplifier over heating.

Hi,grindkin.Not a problem as long as you don't wind the volume control to max.Actually it is better to have more power in reserve to handel the instantaneous peaks of the music. Most modern speakers can handel more than their rated continuous output for a short time. 75 watts at full volume is extremely loud.Most of the time you are listening well below this level.It means you will hear your favorite music without distorsion.I hope this helps.

No, unless you raise the volume level past the point where the sound starts to distort.
Bass levels are specially damaging but 75W is more than enough to send everyone out of the room!

No, just watch your volume setting. The speakers will handle fine, just don't crank them up too loud. If you do crank them up a little, listen for distortion, your speakers will start to sound different when you are pushing the envelope of destroying them.

Too LITTLE power destroys speakers...Not too MUCH power...And click here to see the difference between "PEAK" and "RMS" power...Click right here: http://www.whydoesmyhometheatersuck.com/rmspeak.html

Be careful with impedance of speakers and the amp.
