No need for PT lumber in a weather protected area. You may want to install appropriate brackets to connect the pieces.

As mentioned, think you just need joist hangers in rear like you have up front. It appears that sides have lag bolts hopefully in studs from pics but I could be mistaken. Its built fairly heavy duty for garage storage. If you still feel you need support up front, I'd add storage to ceiling bracing vs below to keep more accessibility and cleaner look.
