Ok, so I've been learning the song Knights of Cydonia and I'm having some trouble with some parts of it.

Slide and Tremolo Pick down the neck.

Right here I'm having trouble with the slide and picking. I just can't seem to get that big slide down (I'm using my finger but would a slide help?). I'm also having trouble tremelo picking the bottom string.

Also at this part...

e|--4--|-----|-----|-----|-----|-----|--3--|-----|

G|--4--|--4--|--9--|--4--|--8--|--9--|--4--|--4--|
D|--6--|--4--|--9--|--4--|--8--|--9--|--5--|--4--|
A|--6--|--2--|--7--|--2--|--6--|--7--|--5--|--2--|
E|--4--|------|------|------|-----|-----|--3--|-----|

I just can't get those barre chords down, When I stretch my finger across the 4th fret and 3rd in the 2nd barre chord. I'm young and I don't know if I just need to work up my hand strength more or what, I'm also having trouble stretching to the frets in the barre chord.

If anyone can help, thanks in advanced.
