Some good videos out there, along with various threads on bicycle sites.
I picked up my cone wrenches years ago, I think they are cheapo Spin Doctor stuff from Performance bike. Nothing special. Don't use them for anything other than cones, they are thin and won't take to being used on any "real" bolts or nuts.
That reminds me, I should probably go through mine, it's been a few years. Oh and you might want to go on ebay or similar and buy a ball bearing kit. The usual advice is, if you drop a ball just toss it. Or just replace in the first place. And don't put in just one new ball with a bunch of old balls as the sizes won't match. I forgot how the grading works but I think it refers to how well matched the balls are to one another--so 25's are better than 100, that sort of thing. Me, I'm not competitive enough to notice so I run just a decent of bearings, nothing ceramic for me.
