I assume you used the Nottingham yeast with the kit? It's temp range is 50-72 so you should be fine on fermentation temp, although it's towards the top of the range. I typically shoot for mid-upper 60's and use a swamp cooler to cool it down in the summer and a heating pad to warm it up in the winter if necessary.
Personally, I would wait two weeks after brew day to take a reading. Even though the krausen has dropped, yeasties are still doin work. When you take a sample for a reading, if you want to be sure it's done, take a sample and then another one three days later. If the numbers are the same, you're done. Two weeks should be more than enough time, so multiple readings may not be necessary. You should probably see something in the 1.012ish or lower range.
