I'm afraid that this is going to be a bit short, but I wanted to start the FDK thread anyway.
Let me begin with what you said last:
As a note, to make sure it is clear that very few good ideas are mine, it was my husband's idea to find some way of eliminating the kryptonite that took a lot of money so that Jimmy could pay for it. I know there are some people who are not exactly fans of Jimmy, but I've always liked him and seen him as a loyal friend to both Clark and Superman. And with Lois already doing so much to help Clark and Perry being the one to find him covered in kryptonite, I really liked the idea that Jimmy can play his part, too and solving this problem is something that is done as a group, not just by Lois and Clark.
I'm not a huge Jimmy fan myself. That means, among other things, that I wouldn't read a fanfic story that focused on Jimmy. But Justin Whalin was cute as Jimmy, and I have nothing against the guy. If your Jimmy is rich, then I think it would be very much in character for him to want to pitch in economically as much as he could to help Superman. I'm glad Jimmy (and Pam) are going to do their bit by providing the plane and the huge piece of titanium.
And I loved this:
“What problems?” Jimmy asked. “Titanium isn't that hard to come by. And neither is a private plane.”
Lois laughed, “You have one, Jimmy?”
“Well, no, but we could rent one and Alice could fly it.”
“Alice?” Clark asked, glancing at the older woman.
Alice smiled, “Well, I could. It's been a couple of years, but my pilot's license is still valid.”
“You're a pilot?” Lois asked, amazed.
“Well, I needed something to keep me busy while Perry was working at the Planet. After the boys grew up, I got bored. I'd always wanted to learn how to fly, so I did. Like I said, I don't get to do it much as it's expensive to get a plane, but I love it.”
Alice is going to fly the plane!!! Yeahh!!!

I'm interested in how you will resolve the B-plot, too.
