You're absolutely right: the rate of SIDS peaks between 1 and 4 months of age and is uncommon after 8 months of age. There's no need to run in and flip your baby onto his or her back.
Regarding the temperature, the AAP just says to "keep the room at a temperature that is comfortable for an adult." Have you tried a fan? Besides keeping the room cool, babies also seem to like the white noise.
It's already pretty warm in D.C., so my baby has been sleeping in a onesie and one of those cotton Halo sleep sacks. She seems comfortable and is sleeping through the night. I stress about her temperature sometimes too, but it helps to remember that if she's ever uncomfortable, she isn't shy about letting me know.
