Please note that our truck's registration [STRIKE]is going to be expired[/STRIKE] in Jun 2010. "is going to expire" or simply "expires"

Regarding the renewal of registration and passing [passing what?], we need to replace some [STRIKE]spare[/STRIKE] parts, and [STRIKE]to[/STRIKE] do some urgent maintenance work [STRIKE]as well[/STRIKE].
You don't replace spare parts on a truck. You replace old parts for new 'spare parts'. They aren't spare when they're on the truck.
You don't need "as well". "Need to [replace ... and do ...]"

So, I took a quotation from the authorized dealer in order to carry out this work; the quotation amount is $0000.00. That's cheap!

Under the circumstances, I would request you to look into this matter and advise me
That's grammatical.

The original uses too many unnecessary words. But it's essentially correct.
