The line should be okay. It's the same as brake line and can twist up quite a bit before collapsing inside. If it is damaged, you will have to cut off the damaged part and re-flare the end with a brake line re-flaring tool. It's a pain to do it on the vehicle but it can be done.
As for the bleeder screw, use two wrenches. One to hold the fitting stationary and another to open the bleeder screw.
