serviceing and general maintance on reels

I've decided to try my hand at cleaning my bait casting reels this winter. I
tried one about 5 yrs ago [el cheappo] and it was never any good after I got
finished. It wasn't any good before but my cleaning did no good. Most of
my more heavily used reels are Shimane 201's -201SF-200 , Chronarchs 101and
a couple of Garcia C-4's[cat fish].I guess what I need to ask is what kind
of tools ,oils etc I will need to have on hand. What web site do you use to
order replacement parts for shimano--diagrams - exploded pictures. ? And
just some general helpful tips on what to look for

Thanks in advance
