Observing NEAs can be fun. On any given night there are dozens of NEAs that are bright enough to observe with a CCD equipped telescope. In addition to the MPC site, if you are looking to observe newly-discovered NEAs, then here are some resources you might find useful::
JPL's Sentry Site:
You can use the JPL page to screen objects that have non-zero probabilities of impact in the future. Getting astrometric observations of these objects can provide one with a personal sense of accomplishment, when your observations are used in the solution that removes an object from this list.
If you are looking for opportunities to observe currently visible NEAs, then Bill Gray's Project Pluto page can help you make selections.

Near-Earth Objects - Dynamic Site:
There is a lot of information here on the NEO impact risk, in addition to many statistics.
