Stay away from the jewelry. Go for a new millennium card. With your first premier and new millennium you will have revolving credit, which when you keep the use to 0-9% of the limit amount you will boost your score. The installment loans do not count as much, so your money is best spent somewhere else.
Congratz on the wells fargo account! Be careful. Even with a second chance account, they can shut it down a few weeks to a few months later just because they feel like it if you are on Chexsystems. So do a search, talk to a credit union, see if you can just get a savings account somewhere to be able to at least cash checks and use an ATM card. And keep a bunch of cash on hand just in case. Trust me. Wells Fargo did that to us years ago, and I still read about it happening online.
Seems like you are in a good position. Its amazing how silly we can be with our credit. My husband and I did the same thing, playing with our credit and just not caring. It can land us in hot water fast. Be happy with how lucky you were to end up with such a small amount. Our current credit report totals (including some stuff that is not ours) totals over 45k.
