OK, I'll take the balances question. It's good to let a minority of your cards post a balance. With two cards, that sounds like 1 with a balance, lol. Probably, but not certainly, your cards report to the credit bureaus on their statement dates, which is when the statement is posted and available for viewing. (Not the payment due date.) About 4 or 5 days before it's going to post, pay it off (if it's the one you want to show a $0 balance) or pay it down to under 10%, which would be under $45 for either of your cards. Once that new balance has reported, go ahead and pay it off and start all over again.
This gets pretty trying with low-CL cards, which is where you are now, but it does work. And in fact, you can use your cards a whole lot more, as long as they allow you to pay more than once each cycle. With discipline and a sharp eye on the calendar, you can put way more than the CL on a card each month and still have it reporting a low or $0 balance. You should get familiar with your online account first, how quickly a payment is credited to your account and so forth, before you get too adventurous.
Leaving the CA questions for those who know! good luck
