If it is to organize your traders, I think you have it in your own OP. The only difference I make is for baseball in that I have them by Sport, Company, Year, Set, #. All products of one company are together. The biggest suggestion I can make is that you order them in the same order as they would show up on this site. It makes it much easier to know when you have gone too far in a box of cards looking for an elusive card. This is specially true for sports you don't actually collect and are less familiar with the cards.
I use this same system in my PC and my sets that are not in binders. I used to have some of my PC of individual players in top loaders and some in binders. I eventually went to all top loaders and these are in the actual order they show up on the site when I look at my collection of that player. No need for any other indicator as to where any specific card is; anything really special such as my 1948 Bowman Musial RC, I know where I have it either when on display or put away for safe keeping.
My sets are also organized the same way. Every set is either in a binder with a suitably-sized card box beside it for the multiple parallels and inserts that are not in the binder. On the shelves, they are obviously organized by Year, the binder first with the box(es) on the right of the corresponding binder.
In being organized this way, I can find any card I have in my set collection, PC, or traders in less than a minute, time being only to unstack the larger boxes of traders till I get to the year I am looking for. I have over 125,000 traders listed (many more doubles in baseball that are not listed so actually have over 400K for trade), My actual collection just went over 300K; this includes PC, sets, and non-sports. So yes, I understand the importance of being well organized.
