Sound advice, thanks!
When you say charge it through the month and pay it before the end, you mean BEFORE the cycle ends, effectively showing 0 usage when it reports..?
I don't think usage really plays into it as much of other factors. I think it's basically length of having good history. I'd say just pay it off completely. It's more than your account is in good standing and for how long, not how much you are running thru it. Really patient is key in rebuilding. It sounds like you'll have most of the negative marks taken care of, but really it's now your time to build good credit. That you can't necessarily force.
I'm not an expert, just going off my experience. Again, I was a dumb college kid that got into credit card debt to help pay for basic expenses and defaulted on them. It took me years of rebuilding credit. Started off with a secured card with a score maybe in the 500s, I forgot where I started. I then got a basic Captial One card, now I have one of the more "elite" cards with a credit limit I'll never use half of it, and now a credit score in the 700s so I was finally get a loan for a house.
It was a terrible feeling when I had bad credit and knew that I wanted to own a house one day. Took awhile, but eventually got there. You'll get there too in time.
