Yes, you need shelves, lots of them, lol. It just amazes me the number of garages/sheds/shops I go into that have no shelves at all.
Shelf brackets can be expensive and the cost can add up quickly if you need lots of them. A nice, low cost solution are these galvanized triple shelf brackets .....

Once screwed to the wall and to the shelf boards, they are pretty sturdy. I used them to put 2 triple shelf assemblies out in my garage. I scrounged the shelf boards from packing crates at work so it didn't cost me any more than about $20.
