Consider storing the less played ones ( but still your not willing to let go off) in a more compact mode (bot or alt mode) and in a secure plastic roller box for safe storage. the rest that are usually played and youd like to keep on display just arrange them in your shelves were they take less space again. as for boxes and cardback and wotnot. if you dont collect em, - bin. if you do collect them , fold and store in another plastic roller box. As everyone mentioned it would be nice to have a designated room for me. If none, cycle your display-storage figures that way it's always interesting to look at and easier to manage.
