The square bracket [ indicating the stat of a beam group should be attached at the end of the first note in the group.

So the part: . . . \bar "||" [ff8 \melisma ef df] . . .

should be changed to: . . . \bar "||" ff8[ \melisma ef df] . . .

Some of the f-flats are not all showing up with flat symbol because LilyPond thinks that you are still in the same bar as a previous f-flat that is marked.

In music notation, an accidental symbol usually effects a note, and all preceding notes in that bar that are in the same staff position.

One option to get more accidental symbols is to use an exclamation point ! directly after a pitch is given.

So the part: . . . ff16 [ef ff8] gf2 ff4 df8 ef ff2. \bar "|" . . .

can be changed to: . . . ff16 [ef ff!8] gf2 ff!4 df8 ef ff2. \bar "|" . . .

However, there are other ways to deal with this problem such as changing the time signature, or setting a different accidental style.
