I was told that when putting my crank back on the bottom bracket to grease the spline area and the bolt. Is this correct? I am having problems with my crank arm coming loose. Ritchey crank on shimano splined bb.

People will argue about greasing square-tapers (I do - no problems so far), but the splined systems are supposed to be greased, according to Shimano.
So, grease away, torque it to spec, and check the torque after a ride or two. If it's still coming loose, you may have damaged splines in the crank, which will hopefully be a warranty issue.
