Slack in steering shaft

I found that the steering wheel on my car was just sitting on the shaft, no nut...ok , no big deal, if I can find the nut (can i get a "help" part for this maybe?)

But I found that I can push/pull the steering shaft in and out about an inch...this movement is at the power steering pump end of things......I also seem to have a small leak there from messing around. Car isnt running yet so cant tell how bad the leak is.....

SO questions:

-Is the slop normal or something that needs addressed? Or will the slack be taken up once I get a nut on it? Or am I in for a repair of the pump and how tough is it?

-If I can figure out a way to do it, can I attach a drill to the pump to similate it working so I can test the pump? I bought new fluid -- Lucas Oil Power Steering Fluid/Stop leak...guaranteed to stop leaks....

Thanks guys
