I had a few queries on the C#5  chord in the orginal tab.
C#5  is just a power chord at the fourth fret A string.
Here it is tabbed out.
   C#5
e-|-----|
B-|-----|
G-|--6--|
D-|--6--|
A-|--4--|
E-|-----|
In addition here is the ending as promised.
e-|-----------------------------|-------------------------|
B-|-----------------------------|-------------------------|
G-|-----------------------------|------x-x-9-9-x-4--4-4-4-|
D-|-6--6-7--7-7-7-6--6-7--7-7-7-|-7--7-x-x-9-9-x-4--4-4-4-|
A-|-7--7-7--7-7-7---------------|-7--7-x-x-7-7-x-2--2-2-2-|
E-|---------------9--9-9--9-9-9-|-5--5--------------------|
   'stoned....................'
    (fades away gradually)
Play that pattern 4 times (not necessarily exactly the same)
and then play these chords. E5  in this case is the first three notes of Em .
A5  E5  B5
Those are the chords that finish the song.
