Course line vs. the Bearing line

[sobe]

I am a little confused.  I know that the dagger on the HSI is for the course line and the triangle is for the bearing.  However, on the HUD, what does the line on the heading scale and the bank angle line represent?  The direction to the course line or the bearing?

The line on the heading tape represents the straight line towards the waypoint, while the bank angle line represents the bank angle (well, yeah...) that you need to have to turn the plane to head the right way toward the waypoint (i.e: it helps you fly exactly on the line between one waypoint and the next one) while keeping the same altitude. It's also doubled on top of the artificial horizon below the hud.
