<human>: Can you summarize the given text in a few sentences?

I had a co-signed credit card as a teenager, and basically was hand-held into having strong credit. I recently got the Chase Freedom because the travel points right now are very strong. 

The card has 0% APR for the first 15 months, provided that the minimum is paid off each month. 

I am planning to buy a $1,300 ticket in the next week, and was thinking of paying off $800, then the rest once the following paycheck comes in (about a week later).

Being that this is my "first" true card, I want to ensure that I don't make any errors when it comes to my future score. I read of "carrying a balance" and I don't know exactly what to make of it. I am financially responsible, and rather frugal at times, yet I am entirely blind to what keeps strong credit. Is it "bad" to pay it all off before the month ends?

I apologize in advance if this is a dumb question, but I feel I should ask so I don't make any facepalm choices in the next couple of months. Thanks :)
<bot>: 0% APR for 15 months, spending $1,300 and am capable of paying it back now, pay all at once or dole it out?
