No tape over the LEDs - don't touch the domes over the chips at all, that can damage them
You are wired in series.
Parallel would be Driver (+) connected to the LED board (+) of both boards via a splitter (or a wire nut connecting the driver wire to the two board wires) and then the same back to the driver from the (-) terminals. This in effect would split the current between the two boards evenly.
You will want to double-check with Steve's to make sure that will work with that driver/board combo. If the driver works with just 1 board and doesn't require 2 boards to work right, then it will work because running 2 boards in parallel is the same as just running 1 board by itself.
