Very good advice so far! I'll only add a couple of things:
1. Boas are not ball pythons! Much of their care is similar, but they act very different. Boas are inquisitive and far less sensitive and do not stress as easily. It was perfectly fine for you to feed her right away. Do leave her alone for at least 48hrs after she eats though.
2. Boas digest their food more slowly so they do not need over-large prey and feeding once every 7-10 days is appropriate for babies. Once every 2 weeks is good for an adult.
3. As Daybreaker said, your temps are way off. I keep my boas a tad cooler than my BPs at 88 on the hot side and about 78 (maybe 76 at night) on the cool side, but cool temps should never fall below 74!! Your boa will eventually start to regurge if kept at these temps and that is a serious issue.
Forgive me, I do not intend to offend, but this last point is something you need to do more than just "keep in mind." This is a serious fault in husbandry that you need to fix right away to avoid serious health issues in your snake. If your temps are as low as you say, a heat lamp alone is not enough to heat her entire enclosure. Please use a UTH on a thermostat.
I have a digital thermometer as far as I know.If you have a digital thermometer, you should not be guessing at the temps. Are you using an Accurite or similar thermometer? How are you measuring your temps? Do not guess - monitering temps is one of the most important and most basic husbandry rules you can follow.and probably around 50 degrees if I could guess.
Again, I mean no offense - I am only trying to help you.
