This is my first day using ShotPro. Better documentation and help would be useful, but even so, it is a very impressive program on the PC.

On the PC, I need to have one of my characters walk the length of a city block.

Is there a way of making this process more efficient, such as guides orrulers of some kind?

My grid is set for one foot and snapping is enabled.

Is there an optimal time interval between keyframes to create a smooth walking animation? Is there an optimal distance to move the character? 

Right now, it's trial and error and with a mouse, I am not getting the same distnace between keyframes and positioning the character.

Are there techniques to simplify this process, getting a character to walk smoothly for a distance?
