Looks good so far. I would normally advise against those pumps since they usually fail after 200 hours (if your using them in your fish tank), but for your specific application you should be fine.
I have pretty much the same setup. Next time I brew some tea I'll snap pics of my farm and setup.
A few tips. Make sure your using "Unsulphured" molasses. I like to use Grandmas all natural. If not the sulphur will kill off all the microbes and render the enter brew useless.
Also it's a good idea to stir the brew to get the molasses in the water column and not sitting on the bottom and place 1 if not both of your air stones right on the bottom also.
In addition to using molasses I read that a tsp of Alaska fish fertilizer per 5 gallons really gives the microbes more than enough food for a 24 hour brew. You'll know it's ready when it's nice and frothy with a good head and no longer smells like fertilizer or molasses.
