Photoshop :: CS2 - Curving Brushed Straight Line?

I am still using CS2, and I am having to break up my desired curved lines by repeatedly using the SHIFT key while clicking the next point along my desired curved line. I would like to know if there is a plug-in that would let me pick the starting point as normal, hold down the shift key while I move the mouse to the ending point, and then,after I click and get the straight line with the brush of my choice, I need a way to BEND that line in the pristine shape of a circular or elliptical arc. I need some way to indicate how much arc angle is needed (from a teeny bit to a semicircle), and also how much to skew it towards either of the end points.

The way I am doing this now is

a) create a new layer and draw the straight line, then, delete everything else on this layer but the line, then show the main layer and edit the 2nd layer with warp, and then, finally, use warp to bend and skew the straight line - after all that, I flatten the image back to one layer. The problem with this method is that warp doesn't hold the edges of my formerly straight line (with crisp edges) true, but introduces indentations and juttings which I then have to go and "fix up" by hand.

b) copy the image to MSPaint, and use the bezier cure to draw the curved line I want, and then, copy it back into CS2.

If there is a way to bend my straight lines drawn with my selected brush, and it would keep the edges crisp and smooth, then I sure would like to learn how. The problem with using "paths" and stroking the path is that I cannot see how it will look while drawing the path and, even after I stroke it, that ugly path line with its anchor and control points muddles the picture and I wind up having to delete it and go back. I need to be able to see the FINAL result of bending my curved line while I am adjusting it with no artifacts to interfere with my close examination of the result.
