Any AVR will be fine with them. So just pick the one that has the features you want within your budget.

The power specifications you state are probably the maximum recommended power. You will also find a minimum power. If you stay within that range you will be fine. If your room is larger than you would lean towards a higher powered receiver.
Be aware that actual power on inexpensive receivers is usually much lower than the power rating you see on the spec sheet. You will find that there are 100 watt surround receivers at vastly different prices and that price difference isn't just for features. Rule of thumb is the heavier it is the better the power will be.
