Anyone know how much this line, and screw? costs and if it is easily available at Advanced Auto or Autozone, Id rather just replace the metal line that comes off right behind the caliper.

 

I actually need the names of these parts.. or part numbers.. I can look up the prices online but I have no idea what they are called... Thank you guys, I hate feeling so ignorant, but this site helps everyday.

 

Always spray brake connections well, tap them a few times, use a box wrench on the fitting, stop if the line is turning with the nut.

You should be able to get the line at the dealer and pick it out in the exploded diagrams. That may be easiest given your concerns and lack of experience.
