Black wire from outlet 1 to top screw of single pole dimmer switch, black wire fr bottom screw of switch pigtailed w black wire going to black wire of transformer (pigtailed w wirenut near transformer) & onto next outlet. White wire from outlet 1 connected w wirenut to white wire in switch box (not connected to switch) going to white wire of transformer (pigtailed w another white wire going on to next outlet). 2 red wires from transformer going to term block, 1 black & 1 white wire from each light goes to terminal block (blacks ganged together, whites ganged together, across from reds).
The first thing that jumps out at me is DIMMER switch. I've never heard of a dimmer that can control a transformer. Make sure your dimmer is really intended to be hooked to the primary of the transformer. Another common problem with low voltage lighting: low voltage cable that might come with it is not allowed to be used in the walls. If you need wiring within your walls for the puck lights, you need to use Romex (or other legal wiring method). Otherwise I think your description of the wire connections is right (a picture is worth a thousand words).
