That timeframe does not seem unreasonable, especially if you are down to 1.006 already. One thing you might want to look into for simple temp control is a swamp cooler setup. I bought a basic Rubbermaid tub that I set my carboy in and then change out ice bottles twice per day in the summertime. I typically fill it to just over halfway up the carboy to keep the temp sticker above the water. It keeps the fermometer in the mid 60's pretty easily, and I can vary the temp by the size of the ice bottle and frequency of exchange.
Also, if you did the extract version, the LME containers make great ice bottles!
