Steering Rack Check...help

So my interior is back together and it's time to move on to other things. It's a rolling chassis, but all of the lines, hoses and other fittings are still intact and in the car. So my question is: Is there a way to check the power steering lines and rack to ensure that all is well. I want to make sure that the foundation is in complete working order before I even consider dropping the motor in.

Thanks

Edit: The closest I got to any kind of check thus far is when I got the car. I had to steer it str8 for the flatbed and steering fluid came out of the lines with every turn. Another question: If air get in it, is there a way to bleed it out?

Thanks HISSIN. Putting in a brand new rack did cross my mind, but the question that follows that is how hard is it to install? And oh yes, that raggedy rag joint is going. That's a definite.
