[s-cars] few basic questions

[Charles Rose]

Hey guys,

I'm doing the first basic service on my car since I've owned it and was
wondering if you guys could help me out with some BTDT info and possibly let
me know if I'm forgetting anything.  I've worked on cars a good deal and
realize these are pretty basic newbie questions but I love my audi too much
to cause any harm to her because I'm too stubborn to ask.  I did try and
search for some info but didn't find much on basic stuff like this. I'm
putting in new brake pads, I just received the mintex ones that I bought
from the s-cars parts direct, I was wondering if I should also replace the
hardware that holds the pads in place, or if there is anything else I should
check out while I'm doing the job?  I'm going to change the oil and filter
as well are there any special washers needed for the oil filter? I have
never changed an oil filter before so any info would be helpful there, what
tools, steps to take when doing this, etc?.  How important is it to change
the washer on the oil drain plug when changing the oil, the reason I ask is
because the closest dealership is quite a distance from me, but if it is
necessary would normal auto stores have these in stock? 

Thanks

Chuck
