Bsurfaces and Line conversion in Blender 2.6.9

There are 3 tasks that my exercises and viewing of tutorial videos havn't helped much on. Could someone
just reply with practical answers, if possible?

-What do I actually do to get bsurfaces generating between two Grease Pencil lines?
I can put down a plane and get the bsurfaces menu to show in the <t> area, but it hangs whenever I get it to go and or does nothing. How do I get it to run and give me the resultant grid, with the new options thereafter?

-What is the keyboard shortcut for subdivisions on a path? How may I select all subdivisions on a path?

-How do I turn a straight, individual path into a bezier, as well as in place too? How may I turn an individual straight path, composite paths, and beziers into a grease pencil line, in reverse (would need to for bsurfaces and other options)? Otherwise what would you do with aid in drawing nicer grease pencil lines?

-What is the keyboard shortcut for subdivisions on a path? How may I select all subdivisions on a path?

Edit Mode > Select segment you want subdivided by selecting the two verts that define the segment > W

Select path > Edit Mode > A
