I told ya!
..wall mounted shelves are the way to go. I'm so glad you are reaping your just rewards. ;)
about the floor-
Block it first!! Whatever you choose to do for a pier, put a healthy amount of cross-blocking in between the joists first (say...every 2-3'. staggered) and I bet that makes a huge difference all by itself. Be sure to use the same dimensional lumber your joists are and be sure the wood is pressure treated.
I would do this: In an area where you have pre-selected to brace with a pier- drop a plumb line down into the soil and excavate a hole with a foxhole shovel that is below the frost line (whatever it is in your area) by at least a few inches and approx 2' by 2' square. Drop a large 18" by 18" patio stone of compressed concrete in the bottom of the hole and level it. Cut a piece of 6X6 PT lumber post that is exactly as long as the top of the stone to the top of your joist and then cut a notch in the post to accomodate your joist. Carefully tap the post in place and drill a 3/8" hole horizintally through the post and joist join and install a galvanized cairrage nut/bolt with fender washers. Double check for plumb and then tighten the nut. Back fill the hole and tamp it hard. 1 of these piers in the right location (after you have installed plenty of blocking) will make your floor rock solid. You can always add as many as you like- but 1 good one should be PLENTY for a room your size.
