Dont' EVER EVER EVER pay the minimum on a large financed purchase or on a credit card, you may be tempted specially if you're starting to make your own money.
It is more recommended to pay more than the minimum, I know financing companies make their money out of interest and commisions charged for such a process but paying things off quickly get you two things: more peace of mind as you get out of debt quicker, and a better credit rating if you ever need it for more important things like studies, specially in the US which is a credit based economy.
It is important to stay as debt free as possible or try to keep them down to a minimum. It is easy to fall for the usual "as long as you pay the minimum everything will be fine" line but if you pay things off by just the minimum you'll end up paying a lot more on interest or be paying those debts for a long time.
The reason why I'm telling you is that unless you have an established credit or an income by which you can handle paying things off as quick as possible you should be careful with credit, in your situation since you're just starting it can be a bit more difficult.
Credit can be a double edged sword, it can help you if you use it right but can be a real pain if you don't know how to handle it. In my case I don't like credit cards but mine has been quite helpful in emergencies, getting stuff cheaper online or getting things I know I can pay in like 2-6 payments or less.
On the other hand, I've seen people racking up large debts because they can be quite impulsive for buying things. I know sometimes credit is the only option and making minimum payments is as well but if handled correctly credit can be your friend.
Just an FYI.
