In How to Brew Palmer suggests that you put foil on bottle place in 350 oven for a minimum of 30 min that will sterilize the bottles and the foil on top will keep them that way until you pull off foil.

I was not aware that palmer said that. I gleaned the info from drew beechum, another all around good guy.

After a 2nd week of bottle conditioning, I cracked a second bottle open and gave it a try. MUCH better taste. A slight hoppiness at the start, then a richness through the middle and end, with a little creamy aftertaste. I like it overall, but its missing that carbonation bite/burn...almost seems a little flat. I decided to give it another week before moving these cases to the fridge, but its well on its way!

I do have a question about my fermenting process though. I got the kit from MWSupplies and was reading reviews, and many of them said they left in primary for only a few days, then secondary for 1-2 weeks. Mine was exactly the opposite because I was in and out of town for 3 weeks while it was fermenting. Does this make a difference at all, or is it good as long as it gets the time to ferment?

Unless you are doing an actual 2nd fermentation with new sugar or new yeast/bugs, there is not reason to transfer to a 'secondary'. Your beer is likely better off than those that took the beer off the yeast after only a few days.

You should be fine. Three weeks is perfectly fine and I think most/many folks around here would say a secondary is not needed for a beer like that.
