I'll tell you what I think, because that Capricorn Jupiter of yours is similar to mine, though not quite. (I'm not an Astrologer btw.)
As for your second question, I think you already know what is required of you to actually become rich if you're not already born rich.
Jupiter in Capricorn (in fall), realistic mindset. Hard work, hard work, hard work. That goes for everyone, but this sign knows it especially. You'll find that you receive more luck by incorporating the traits of Capricorn: organizing, being honest and ethical, taking a disciplined step-by-step approach. And this will be within the themes of your 6th house, routines and daily work among other things... I would say this is generally a good placement! Do you know which career path you want to go?
Your 11th house of gains, its ruler in your 2nd house of earnings and finances could mean that you'll have a lot of acquaintances at your disposal ready to help you gain success. But it'll depend on your goals and if you want to work for it.
