Whether you're playing as Leon or Claire, the solutions remain the same and can be accessed without grabbing the memo that hints at their solution. The only exception to this are the items you grab by developing film rolls--though, there is a minor exception even to that. Regardless, below you can find details on all the optional items locked behind safes, lockers, or hidden in the environment.
Gun lockers or safes are specifically designed for the secure storage of guns and ammunition. They broadly resemble normal single-tier lockers, but tend to be slightly less high than normal single-tier lockers, and are often free-standing, and not banked together. They are fitted with internal racks designed for holding firearms. They have a shelf at the top like normal single-tier lockers, although in this case it is closed and locked by a separate door, because of legal requirements in some countries that firearms and ammunition be stored and locked separately. They always lock with three-point locking, which is in some countries a legal requirement for the storage of firearms. Sometimes they are made of the standard kind of sheet steel used in manufacturing normal lockers, and sometimes they are made of extremely thick heavy-duty steel and in this case resemble a safe more than a normal locker. In Australia there are strict regulations governing the storage of firearms following the Port Arthur massacre in Tasmania, Australia on 28 April 1996, and cabinets used for storing firearms must be bolted to the floor or a wall if the cabinet is under a certain weight. Dedicated gun lockers are likely to include holes in the cabinet to accommodate such bolting. Several locker manufacturers also offer dedicated gun lockers.

Examine the scepter to obtain the Red Jewel. This goes into the Bejeweled Box, which you can get in the Interrogation Room. Accessing this area requires the Club Key, so if you don't have that yet, keep progressing the story until you get it. Once you've got the Bejeweled Box, combine it with the Red Jewel to get the S.T.A.R.S. badge. You can use this item in two locations: the Underground Stairs in the Middle section of the Underground Facility, and the S.T.A.R.S. Office.

For longer term storage, there are many self storage units around the metro area. Not cheap, but then neither is paying extra baggage fees and lugging around extra stuff not needed for another leg of your trip, as it sounds like Terry might be doing. For example, I found "Downtown Denver Self Storage" with units starting at $45 a month. http://www.downtowndenverstorage.com/
