Assuming that you can identify (know the names of and can find on the keyboard) the notes on both the treble and bass staves (which are connected by a bracket and which together make up the grand staff), there is one line between the treble staff and the bass staff, and that note is middle c. Then the first notes in the first measure bass staff are c (second space from the bottom,g (top space), and the next 3 notes are the same as the treble staff: d, e-flat, and g. Does that answer your second question? And what was the first question about what's going on in the second "line"? And by "line" do you mean measures 5 through 9, or the base staff of measures 1 through 4?
Music notation is very logical, but there are many details to learn. Beginners usually do best with a teacher.
