The stickies at the top of this board have a ton of info. This is of course assuming the First Act does not have any wonky frets or other issues. I'm not bagging on First Act, but other than their premium basses the lower cost ones get mixed reviews at best.
It may be difficult to get a good set up on a wonky bass. it will be good practice for you as you won't break down and cry if you screw up the truss rod in the First Act.
Another thought, maybe take the bass to your local tech and have him walk you through a set up..if they will do so.
Also you need to be aware of single action and dual action truss rods....and which ones your basses have....
