Only if the calculations require it.
If I were you, I'd try brewing a nice, low-gravity ale without a lot of complexity. Put the fermenter in a swamp cooler and monitor the water bath temperature with a good thermometer. Calculate the correct amount of yeast to pitch (I use MrMalty), rehydrate properly, aerate thoroughly, and pitch. It sounds like you're already doing the main things correctly, I'm just wondering if doing a simplified recipe might help isolate the problem.
