I think Imran and Will have pretty well answered the interview lighting question for Lisa, so let me talk about the chroma key situation. Lisa, the most important item for pulling a good key is to have the background lighting as flat as possible. Now, I have never used the JTL lights for key purposes, but I have used other soft lights, and they can work very well in keys.
Depending on the area you need to cover with your green screen, you could use one or two of the JTL lights. If you are doing a reasonably tight head shot, try to get about eight feet of separation between the subject and the background. The best location for the background light would be hidden behind the subject, if possible. Point it straight at the background and you are good to go. Light your subject using one other JTL for the key light, at about a forty-five degree angle from your subject. Then use the third JTL for a kicker. Place it behind the subject, off to the side opposite the key light. This will give you a nice partial backlight, and a bit of warmth on the off key side. You can adjust this light to taste. You might want to add a bounce board on the opposite side of the subject.
If you need a wider shot of the subject than above, you can use 2 JTL lights on either side of the subject, pointed at the screen. Try to get the light effects to overlap slightly, and create a flat effect on the background as best you can. This will leave you only one JTL for a key light, so you may need to invest in another light for a backlight or kicker. I suggest the LTM Pepper 400 as a fine investment for the future. It will run around $300-400.00 depending on how many accessories you purchase with it. You will also need a stand for it, or a "boom" if you want to hang it directly behind the subject. That's the basic way to get the backlight effect, but I find it kind of boring.
That Pepper makes a nice addition to the JTL Everlight Kit. You can take one of the JTL lights out of the kit and replace it with the Pepper, and you have a really good kit all in one container. Use the third JTL stand with the Pepper.
BTW, keying is a real art, and you are always well advised to shoot some test footage before doing anything important.
Have fun
