Translation Help: AP - Yaro Yarodi

[Akki]

Hi,
I need help in translating some Tamil
lyrics into 'correct' English.
The lyrics are below, with English
translation according to the dvd,
but a couple of things don't make sense
to me.
Could someone please help me out?

I would like to know if the translation
is accurate. If not, a correction will
be more than appreciated.
Also, can anyone answer the questions between
the brackets?

Thanks a lot
Akki

(PS: More lyrics posts will follow)
