I've found the most effective way is to use album sheets in a 3 ring binder.
The 4x5" sheet size cards can be stored in 4x5" album sheets (4 to a page..you'll have to order these, but I guarantee you'll love having them for the career sheets, etc.
The little cards fit great 2 to a slot with regular card sized album sheets.
I don't store the basic action cards. I stick them in a zyplock along with other stuff that I don't need sorted. I use my Adventurer's toolkit box to store my dice and have the stash out in front of everybody.
Lastly, I HIGHLY recommend using an album sheet for your players to put their cards into as well as simply a zyplock (gallon) for each player rather than those dinky little tuck boxes.
