Are you handling the snake at all? If so, try leaving it alone until it eats. Handling the snake before it acclimates (and acclimation means it's eating regularly) can stress it out more and cause it to not eat.
Also, I read that your temps may be too cool. You can also try a UTH (under tank heater) instead of most of those lights. I've found that lights tend to dry out the cage unless you live in a VERY humid area (I'm talking tropical like Florida!), and even then...Why provide a basking area for an animal that spends most of its time hiding in a rodent hole in the african scrub? Belly heat tends to work best...at least in my experience. If you're worried about how hot the UTH gets, get a dimmer from Home Depot. They work GREAT for a single heat pad.
Keep the thermometer/thermostat an inch or two above the bottom of the cage - that's where the snake spends most of its time anyway!
What part of the house is it in? If it's in the living room, where a lot of people tend to go through, try moving it to a bedroom or somewhere that doesn't get much foot traffic.
The petstores are confusing about the feeding in a separate container thing because people tend to be divided about the issue.
Some people say do it, some people say don't... Pretty much, the theory is that removing the snake from the cage will help to condition it not to expect food every time you open the cage. However... Before I learned about all this, I fed my female in her cage for about 14 years. I can count on one hand the number of times she's bitten me...and all three times, it was right after she'd been fed (still in feeding response mode), and I had not washed my hands prior to sticking them back in the cage.
Pretty much, use some common sense, and feeding in the cage is really not that big a deal. In your case, I would feed in the cage until the snake is eating. Removing it from the cage is a stressful event, so it is probably freaking out about being out of the cage instead of focusing on eating.
Warm up the snake, leave it alone, and try feeding in the evening in the cage with a live prey item. After 15 minutes, take the prey item out, and try again in a week. 
If the snake has good weight, it can take a couple months without food just fine.
